Yes. A failed attempt is still a useful signal that people shouldn't try to simplify back to that way in the future (and why not). It's also a useful starting point in case the reasons it failed no longer apply.

It's very rare that "failed attempts" are a useful signal. When it is the case, it's better to document it (eg. as part of the commit message, PR, or the dev documentation itself).

Commit histories littered with commits that get back-and-forth reverted are frickin unreadable though. Extremely annoying to bisect, painful to comb through when looking for changes, noisy in git blame, etc. There's a ton of downsides for what in practice is very rarely even an upside.
