This is still really rough. I see lots of "why?" questions in the comments here, so I'll tell you what I immediately thought of -- getting close to a container system on an iPad Pro would be really amazing. For a while I traveled with just an ipad pro for work, and one of the largest pain points was the lack of any real OS for work without ssh-ing somewhere.

That said, my vibe is that by the time this matures enough (and Safari on iOS works well enough with it) that it's performant, there will likely be another solution that's better.
