git send-email's capitalization does annoy me and I've looked
into changing it; but there's a bunch of tests and probably
dependent code that also need to be updated...

It does annoy me, too, and I do not mind if it gets "fixed", but I
do not know if the cost for vetting a bulk update like that is worth
it.  There is another one outside send-email in log-tree.c that is
responsible for output from format-patch.

I support updating the documentation in git, first; then perhaps
making tests case-insensitive (which could be a complex
change...).

Unfortunately, changing the send-email + log-tree.c code would
break existing users of the applypatch-msg hook sample in
linux/Documentation/maintainer/configure-git.rst which has
been case-sensitive for around for 2 years:
