It may be prudent to note that git by default is rather kind in that way that it will not change your data unless you explicitly force it to with --force or --hard. I think git, as hard to learn as it can be, sometimes have a bit of an unfair reputation here. It's not all bad.

Not only is it quite careful about not losing data, someone actually took the time to make it spit out messages that not only describes what just happened, but also gives suggestions of what to do next depending on how the user wants to proceed. That adds a level of discoverability that is usually associated with dialog based guis. The quality of these messages can sometimes be surprisingly good, far from the Clippy-level helpfulness you sometimes see.

There are a few exceptions to the principle of not losing local changes, where you explicitly restore an old version of a file for example. But saying the default behaviour is destructive really gives a false impression.

But yes, you are absolutely right that a system to recover unsaved work is a good thing, but I would argue that it belongs at the editor level, not in a version control system. A user could have a number of files open that have local changes. The editor has a much better idea in which order changes were made, and which changes hasn't even been committed to disk yet.
