Uh, the idea to warn comes from previous comments I wrote 25 days ago:
"and maybe we could warn client in fetch-pack stage, if we don't choose
to reject shallow cloning."
then no one response to that point, so I think is ok to apply it.
Now, it seems like a bad idea. I will remove it.

Yes, this is for protocol v2.

Ok, will do.

Yes, exactly.

I will remove the unnecessary warning() part.
Thanks!
