"nobody guarantees" just means that you can't externalize the work of trying it and seeing if it works. I don't think that's a huge loss, considering the space of all possible kernels, configuration switches, patches and distro packages is huge.
It's like refusing to use a hammer because nobody can assure you that hammer A was thoroughly tested with nail type B.
No, its like using a nailgun A with nails Y when it's only guaranteed to work with nails X. Or like using a chainsaw A with chain Y when it says you should use X. But hey, at least you are not trying to use nails on a chainsaw... ;-)
No. It's like shooting yourself in the face because your friend survived it.
In fact, nobody guarantees that say Fedora will run on an Ubuntu-built kernel. Or even on a kernel from a different version of Fedora. So, IMO, anything other than running the exact same OS on host and in container is a hack.
