Is (3) a real problem? After Linus' strongly-worded[1] email, I assumed kernel backward compatibility was fairly robust. Isn't it?

It doesn't appear to be a problem. We built something relatively similar to this where I work, but with generic Linux utilities like chroot. We have 11+ year old Linux environments running on RHEL6 just fine.

The other is not so easy, very recent Linux environments don't always run on RHEL6.
