I can't say I've observed that to be the case with Btrfs.  I know
there is a core group of developers working very hard on testing the
Btrfs updates in the _rc kernels, but once that .0 kernel hits the
streets, the extra exposure to all the various combinations of
hardware and options has been know to discover new issues.  I think
this is nearly unavoidable given the pace of Btrfs development.
