Unless there's a huge performance win in having FS-level encryption - I fail to see why *any* FS should have its own encryption support.
Instead of solving security and performance issues in one layer (dm-crypt) you are now forced to solve the same (?) issue across different FS' (ext4-crypt, btrfs-crypt, etc).
Granted, all FS' can share the same crypto code and implement it differently on disk - but this will be more-or-less the same as improving dm-crypt (which in the case of btrfs COW, may be a hard requirement).
