humm... what build.git ? :-) on master I do not even clone build.git anymore...

some people... git + submodule at that scale will be much worse
Con: it would be using submodule in a way it was certainly not
intended to be used. That means that doc and support for that will be
scarse and chance of screwing things up rise big time, with very few
'expert' - if any - to sort things out.
Con: how well is it going to mesh with the fact that some git repo are
'optional' (l10n) ?
Con: that will probably mess with the hg import script. we would need
to make sure that import is still feasible - without breaking the
current history

Note that the main drawback of our current approach is indeed the
bisection problem. It would be certainly be convinient to be able to
bisect on the entire set of repos... but how much pain/risk do we want
to take to improve that aspect of things ?
