Sure, this is another approach. I still wouldn't like the feature
removed until there's something or other implemented to replace it. :-)

The semantics of ${phase}.asroot are not desirable for this purpose, as
it actually makes it impossible to run the phase with a non-root
installation. The comments around the elevateToRoot in destroot also say
something about mtree; not really sure what that's about.

It would still be necessary to become root at the very end to chown
everything to ${install_user}:${install_group}.

Quite true.
