If a merge conflict occurs, I'd much rather hear about it from git instead as opposed to some obscure breakage later in testing or production.

The merge conflicts tend to be things like library updates or large scale refactors. It's massively easier to update a core framework 20 times than it is to do it once on a repo 20x larger due to merge conflicts and the minimum possible work being 20x larger.
