I've been on a maintenance team for years and it's also been a massive help here, in our svn repos where squashing isn't possible. Those intermediate commits with good messages are the only context you get years down the line when the original developers are gone or don't remember reasons for something, and have been a massive help so many times.

I'm fine with manual squashing to clean up those WIP commits, but a blind squash-merge should never be done. It throws away too much for no good reason.

For one quick example, code linting/formatting should always be a separate commit. A couple times I've seen those introduce bugs, and since it wasn't squashed it was trivial to see what should have happened.

I agree, in a job where you have no documentation and no CI, and are working on something almost as old or older than you with ancient abandoned tools like svn that stopped being relevant 20 years ago, and in a fundamentally dysfunctional company/organization that hasn't bothered to move off of dead/dying tools in the last 20 years, then you just desperately grab at anything you can possibly find to try to avoid breaking things. But there are far better solutions to all of the problems you are mentioning than trying to make people create little mini feature commits on their way to a feature.

It is not possible to manually document everything down to individual lines of code. You'll drive yourself crazy trying to do so (and good luck getting anyone to look at that massive mess), and that's not even counting how documentation easily falls out of date. Meanwhile, we have "git blame" designed to do exactly that with almost no effort - just make good commit messages while the context is in your head.

CI also doesn't necessarily help here - you have to have tests for all possible edge cases committed from day one for it to prevent these situations. It may be a month or a year or several years later before you hit one of the weird cases no one thought about.

Calling svn part of the problem is also kind of backwards - it has no bearing on the code quality itself, but I brought it up because it was otherwise forcing good practice because it doesn't allow you to erase context that may be useful later.

Over the time I've been here we've migrated from Bugzilla to Fogbugz to Jira, from an internal wiki to ReadTheDocs to Confluence, and some of these hundreds of repos we manage started in cvs, not svn, and are now slowly being migrated to git. Guess what? The cvs->svn->git migrations are the only ones that didn't lose any data. None of the Bugzilla cases still exist and only a very small number were migrated from FogBugz to Jira. Some of the internal wiki was migrated directly to Confluence (and lost all formatting and internal links in the process), but ReadTheDocs are all gone. Commit messages are really the only thing you can actually rely on.

Lets just be Bayesian for a minute. If an organization can't figure out how to get off of svn, which is a dead and dying technology within 15-20 years of it being basically dead in most of tech then probably it's not not going to be nimble in other ways. Probably it's full of people who don't really do any work.

Dude this is what I mean. How did someone manage to mess this up? It's not exactly rocket science to script something to suck out of one wiki and shove into another one. But lets say it's hard to do (it's not). Did they just not even bother to look at what they did? They just figured "meh" and declared victory and then three were no consequences, nobody bothered to go back and redo it or fix it? Moving stuff between wiki's is an intern-skill-level task. This is another example that screams that the people at your work don't do their jobs and don't care about their work, and that this is tolerated or more likely not even noticed. Do you work for the government?

I suspect you are exaggerating how reliable your commit messages are, considering.
