Its easy, i branch to change the submodules so when i update it i keep
the master clean. Most if not all my changes are minor things that are
specific to my setup, or patches sent by others that i found usefull and
upstream didnt merged it yet mostly cause its not mature.

I see, this is more feasible in the case you think your hacks are worthily

this is very nice and flexible, thank you for taking the time to
explain, understanding the 'better' workflow is always nice.
