Yes, you have use cases, but you never answered the question I asked:

Is this going to be enabled by every distro kernel, or is it for special
use-cases where only people doing a very specialised thing who are
willing to build their own kernels will use it?

Saying "hubble/tetragon" doesn't answer that question.  Maybe it does
to you, but I have no idea what that software is.

Put it another way: how does this make *MY* life better?  Literally me.
How will it affect my life?
