That's fine, I think ideally run_hook() should call warning() for each case which may be returned. Such functionality is already available in builtin-receive-pack.c::hook_status() and unpack(), probably it would make sense to introduce some run_command_strerror() to avoid code duplication.
Sadly I don't have time to implement this in the near future.
