We all now do, of course

I guess you’ve never kicked ass and chewed bubble gum

Same. Is there a project page or anything that explains the context, the reasons, the history behind this? I bet it would be very interesting.

The Readme is too technical and misses a writeup on the soul of the project: Section 1, title. Section 2, already talking about Ubuntu and dependencies. Where is section "Why?" :-) ?

In addition to those categories, speedrunning glitch hunters tend to gravitate to participating in these projects as well. E.g. the Twilight Princess decomp was started primarily by and for the speedrunning community.

You can definitely do a lot of relabeling that way. It may be also worth trying a loop of "fix until it matches binary" for separate files... But I haven't seen anyone actually write it up.

There are attempts like this https://github.com/louisgthier/decompai that are related, but not quite the same as this project.

Edit: just gave it a go, and guessing reasonable variable names works extremely well when there's partial information already available. Especially nice for things like naming all the counters and temporaries when you know what you're iterating over, but can also figure out the meaning of larger patterns for function names.
