Yeah, I have the same experience. Historically I've had my IPv6 down for 
days before I actually needed it to ssh home to one of my devices. HE 
solvs most user issues.

Only thing that makes it break is if there is PMTUD blackhole. So better 
to stop IPv6 (or IPv4) working completely, than to introduce PMTUD
