It won't be able to extract the required information, because it will
not exist anymore. But, as that code is checking for nil, it won't
break. Your change will make it break:

(setq emacs-repository-version "fce2a09142ddccc242931edd16712c2c24e10e8e")

Switching to Git with remove some functionality (specifically, being
easily able to check how many commits there are between the compiled
Emacs and the repository head). That cannot be helped, sort of looking
for alternatives. I'm not complaining about lack of functionality, but
code breaking.

But anyway, that's not even the issue. The issue is that we had an
interface which said that it would return a string with some format,
or nil. You want to keep that interface, but make it return something
different. That's incompatible *and* unnecessary. And you seem to
insist just because you don't like the idea of the old APIs being
around in loadup.el?
