For zfs specific features, there are 'zfs' and 'zpool' commands (well, binaries, and the first parameter is a command). For btrfs, there is 'btrfs'.

So I guess that the GP considers /usr/sbin/{zfs,zpool} more intuitive than /usr/sbin/btrfs.

Well zpool is for the pool which consist of filesystems/datasets or zfs's. So i have a clear distinction of the whole pool (pools or logical groups) or filesystems/datasets (zfs or logical volumes).

It has nothing todo with /usr/sbin/x
