Well, that's not strictly true. Being able to make such adjustments is
part of the reason for the separation between git submodule init and git
submodule update. After init you can go in to .gitmodules and edit
URLs, etc. I admit that can be painful compared to just doing a
recursive clone.

Why is that? Because it's possible to commit through https?

No problem, if that's the right answer. I think you just need to edit

But won't someone complain that they can't access https behind their
corporate firewall? It always seems like there's no right answer in
this territory.

Oh, nifty; I didn't know about this!

Given the propensity of various access methods to fail for various
reasons, I think we probably ought to suggest the use of insteadOf right
in the instructions, no matter how we decide to write the URIs.
