Hmph.

I wonder if rewording the message when git-shell-commmands directory
is not there may be a better first step (which actually could be the
last step)?

That is, showing something like this,

> +printf '%s\n' "Hi $USER! You've successfully authenticated, but I do not"
> +printf '%s\n' "provide interactive shell access."

but rephrased with a reference to "git help shell" for people
preparing their own server when ~/git-shell-commands/ in good order?

Something like

diff --git a/shell.c b/shell.c
index 84b237f..71ff04f 100644
