Seems like a good general advice in most cases

Disagree with implementers coming after authors, profoundly.

In the movie Tron, a user is this worst thing a program can encounter.

> Greetings, programs! Oh, what an occasion we have here before us. Because your rumors are true. We do indeed have in our midst a User!

(Can't find the 1982 quote, but this one from some 2010 redo gets the point across)

There are billions of users, probably 10's of millions of people of people writing html, 10s of thousands of implementers and 100s of designers.

A tiny improvement for a huge group can outweigh many drawbacks for a smaller one.

But when designing a standard, if you ignore the needs of implementers you can accidentally write yourself into a place where it becomes impossible for new implementers to completely implement the spec, so we're locked to our existing implementations.

I don't think that HTML has this problem so much, but it's absolutely an issue with both CSS and JavaScript.

It's probably right in this context, but I'd be careful with the last part in general contexts: assuming utility is linear makes for easy reasoning but also would say that a mild stomach ache for every single human (i.e. 7*10⁹ stomach aches) is worth more than the life of someone.
