And they can.

[However, I don't see the point for it. Apart from ideological considerations,
there is no obvious advantage to the split-usr layout anymore.]

Yes.

That is the imho more important and valid point, maintaining the remaining 
split-usr installs will get harder.

For amd64 and arm64 that's doable (since builds are cheap there).
I would very much discourage using these variants for new installs though.

[And yes I would prefer to deprecate the split-usr profiles and remove them
at some point in the not-so-far future. That is however a topic that needs
separate debate.]

The decision where this is going has been made long ago... just not by us
because we've been lagging behind. But I get what you mean.
