Side note. Here is what dc87183 says:
commit dc87183189b54441e315d35d48983d80ab085299

Only use GIT_CONFIG in "git config", not other programs
For everything other than using "git config" to read or write a
git-style config file that isn't the current repo's config file,
GIT_CONFIG was actively detrimental. Rather than argue over which
programs are important enough to have work anyway, just fix all of
them at the root.
Also removes GIT_LOCAL_CONFIG, which would only be useful for programs
that do want to use global git-specific config, but not the repo's own
git-specific config, and want to use some other, presumably
git-specific config. Despite being documented, I can't find any sign that
it was ever used.

It clearly explains the reason why LOCAL_CONFIG was removed (the reader
does not have to agree with "I can't find any sign that it was ever used",
though), but I cannot read from the first paragraph the reason why it was
felt necessary not to honor GIT_CONFIG in other programs, i.e. "was
actively detrimental" is not backed by any example in the paragraph. I can
sort of sense from "Rather than argue over..." that there may have been a
discussion on the list, and reading the archive from that timeframe may
reveal why many felt it was not a good idea.
Daniel, do you recall the context?
