On the other hand there is concern that those security modules might
be abandoned if they have to wait until everything is finished :)
There is some truth to that. If we can get commitment from the developers
of those security module to push for getting upstream, a statement of
intent to support additional modules (e.g. Landlock, S.A.R.A.) from a
significant distribution (e.g. Fedora, Ubuntu, SuSE) and ACKs from the
maintainers of the existing modules we should be able to breeze right in.
Yeah, I think that's about all it would take.
