I like the general direction this is going, but:

Doesn't that mean that people who currently do allow interactive access
and have a ~/git-shell-commands/help (that returns zero) will get
spammed by its as a motd each time they connect?
To be honest, I am not really clear on what interactive git-shell is
used for. AFAIK, it does nothing unless you have set up custom commands,
and I have never actually seen them in the wild. So maybe it is not a
big deal.
If I understand correctly, calling it "check-interactive", "greeting",
or something instead of "help" would be sufficient, and then you
wouldn't have to worry about backwards compatibility.

This kicks in only when there is no command given, right? So if I ran
"ssh example.com", it would give me the help message rather than (or in
addition) giving me interactive access.
What about "ssh example.com foo"? Do we want to allow a custom message
there, too (it might be different there; e.g., an allowed list of
commands might make more sense)?
