I'm not convinced --- I don't see much value in trying to preserve MAC semantics over load/unload of different security modules, so for sanity the important thing is just to be able to detect whether a security xattr "belongs" to the current module or not. That can be done with a simple prefix in the xattr value itself. Trying to make multiple MAC labels coexist in different xattrs seems to have little use.
