What kind of regression?

Sure it won't break anything, but it won't work either!  The existing 
message hook runs after the editing session -- I want the hook to 
introduce text that is merely a suggestion that the user can delete, or 
a template that the user needs to customize further.

How does adding a new hook affect existing hooks?

Please.  That's ludicrous.

My patch is 3 lines of inserted code and 0 modified lines, checking one 
variable that is set once in builtin-commit.c (edit_message).  The 
documentation says that it runs whenever the editor runs except for -c, 
and launch_editor runs after the 3 lines of code I inserted.

Seeing how biased you are, I don't really know why I bothered answering you.

That's the first sensible argument that I hear.
