Very strong agreement here. My 2c is that Yocto/OE should be going in that direction even
further. One of the significant benefits of the OE build method is eliminating, to the greatest
extent possible, the (usually) undetectable influence of variations in the host platforms.

Any given distro is probably stable enough, but that does not guarantee a consistent result if
we attempted to build the same image on all available stable distros. We might get lucky and
actually achieve that, but I would not bet my life on it, particularly if we started using even more
native tooling.

"Stability is a local construct, not a global one."

For our own project, we have taken this as far as practical. We eliminated the third party
distro host platform (Ubuntu) about five years ago and built our host platform from Yocto/OE
sources. Each new version of our host platform is built from the previous one.
