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.
