Normally I'd consider this a problem but the current behaviour is the
intended one, just back when the code was written thre were no changing
default yes

long-term. Given that btrfs isn't clasified as stable, I consider this
behaviour change acceptable and it's better to handle this now rather
than perpetuating the issue.
