At this point it is, aye. A hard Brexit seems like it can't be implemented due the Northern Irish issue alone, and even beyond that it'll cause all sorts of upheaval. Politicians complaining about how they won't be able to end freedom of movement should've considered that in the years during which they'd been arguing against the EU and had been expressing a desire to leave.
A soft Brexit is pointless, in that we'll basically remain in our current situation only without any leverage whatsoever over the EU, but I'd rather that than chaos.
