I'm not sure in what sense this is an improvement (similarly with recent
BCC -> Bcc, etc), but it is inconsistent with existing usage.
In current emacs-26:

find . -name '*.texi' -exec grep 'Mail-followup-to' {} + | wc -l # 2
find . -name '*.texi' -exec grep 'Mail-Followup-To' {} + | wc -l # 20
find . -name '*.el' -exec grep 'Mail-followup-to' {} + | wc -l # 0
find . -name '*.el' -exec grep 'Mail-Followup-To' {} + | wc -l # 50
