I read a some time ago about them working AltOS mode, for Chromebooks, that was going to make installing other operating systems easier. Not sure what happened to it though.

For me I won't mess with a Chromebook until they've consolidated Android and ChromeOS into a single platform (likely Fuchsia). Until then I don't expect any real support for edge cases to be adequately addressed. It will always "kind of but not really work" because Google's already working to replace it with something different.
