True, we don't make any guarantees regarding code that hasn't been
released via Linus' tree and right now the extended socket class patch
is just sitting in the SELinux tree.  That said, I don't consider it
major problem to introduce another policy capability if needed; it's
definitely cleaner not to have to do so, but I wouldn't consider it
reason to rush the SCTP support if it isn't ready.
