Adding the compression types makes sense for the UAPI, Qu has sent patch
to move more code to the exported headers ("btrfs: move on-disk
structure definitions to btrfs_tree.h"), including the compression type
definition.
I'd prefer to move the code in a bigger chunk than one by one, unless
it's breaking compilation.
