If by "This" you mean the "Server does not allow request for
unadvertised object",
then that (force-push) may not necessarily be the case. It happened to me and
my colleagues while using big repos with submodules where
neither superproject nor submodules allow force-push.

I've not yet managed to figure out what caused those issues, but fiddling
with updates using usually solved the issue.

git submodule sync --recursive
git submodule update --init --recursive

The git pull alone is hardly ever useful command while working with Boost
superproject or any non-trivial superproject. In most day to day tasks,
one will need a script for smooth updating operations.
I always update Boost with mine
and I don't recall I ever encountered any problems.

Yes, it is a good idea.
Boost.GIL and Boost.Geometry disabled force-push for both branches.
