There is a certain subset of our users who routinely compile from 
master, but don't really contribute to the development.

For instance, see the Homebrew stats here for 'emacs --HEAD':

https://formulae.brew.sh/formula/emacs

(I don't really have any numbers across platforms, this is just the 
first thing I managed to dig up).

Hmm, maybe I spoke too strongly. I haven't tried a full AOT build myself 
yet, actually (Stefan showed some numbers on that), but even the current 
"lazy" approach feels quite slow to me.

So if you have ever been annoyed with the current recompilation speed 
after 'git pull' (even just of the files that do need to be recompiled), 
you can multiply that time by X.
