Most distros have infrastructure in place to handle quick updates to the 
kernel, and tend to keep the kernel up to date to fix hardware issues 
that affect people who may not be using BTRFS.

In contrast, btrfs-progs updates generally aren't high priority, because 
they benefit a much smaller user base (unless you're SuSE).
