Yes, but why is that a show stopper? It's a small market filled only with people who typically have large fist-fulls of cash and are dependent on version control. It's a small market, but companies in it have the resources for a good solution.
Because those companies generally already pay the $$$ for Perforce (which has any number of deeply terrifying, shiny red candylike self destruct buttons and makes git's user interface look kind) which for all its other faults handles this specific user case extremely well.
