Well, no, you're getting cause and effect mixed up, there. RH doesn't
have btrfs developers on staff *because* RH, over time, has broadly
come to the conclusion that btrfs isn't the storage tech it wants to
roll with. It's not that RH can't support btrfs for paying customers
because it has no btrfs devs, it's more that RH has decided it doesn't
want to support btrfs for paying customers so it doesn't hire any btrfs
devs.
