So from reading your discussion, the user expectation is to have
`git submodule {init, update --init, sync}`
to pay attention to url.<base>.insteadOf when setting up the
submodule.<name>.URL, such that the modified URL is used for the
initial clone of the submodule (and hence any subsequent usage within
the submodule).

That sounds like a good idea to me.

Two caveates:

* After running `git submodule init`, you change url.<base>.insteadOf
  in the superproject. How do we need to word the documentation to
  have users expecting this change doesn't affect submodules?
  (See above Any vs. "Any except (initialized) submodules")

* So with the point above the insteadOf config only applies to the
  init/sync process, (i.e. once in time, ideally).
  Is that confusing or actually simplifying the submodule workflow?

Thanks,
Stefan
