I don't think this is quite correct.

The alternative is to engage with the kernel community to become part of 
the development process, to ensure that appropriate APIs are implemented, 
and to get code upstream before shipping it.

In any case, a patch to revert the dynamic aspect of LSM has been posted 
by Arjan (and acked by myself) for the case of valid out of tree users.  
The only case of this so far has been Multiadm, although there seems to be 
no reason for it to stay out of tree.
