For better or worse, there is a long history of the upstream Linux
Kernel focusing only on in-tree kernel code, I see no reason why we
should change that now for LSMs.  I am sorry that this approach
negatively affects the LSMs you mentioned, but if they are not
interested in being merged upstream there is not much we can do to
help.
