This PostgreSQL patch hasn't seen any production use, either. In fact, 
I'd consider btrfs to be more mature than this patch. Unless you think 
that there will be some major changes to the worse in performance in 
btrfs, it's perfectly valid and useful to compare the two.

A comparison with ZFS would be nice too. That's mature, and has checksums.
