Yes, I'd much prefer that.  That package definition might not be able to
infer certain things, so we'd need to be able to specify e.g. paths to
include in the container.  Preferably overridable as well---for example,
I don't share ~/.cache/mozilla/icecat with the container (I want it to
be ephemeral), but other users may prefer to.

I agree for my needs; I suppose we'd need to see what downsides exist
from containerization (if any) that might make the user think
otherwise.  If containerization by default is suitable, then there may
be no need to provide a non-container option, so long as the user can
choose paths to share with the container (and network access).  This is
sounding more like an AppArmor type of permission system.  (Without the
AppArmor, of course.)
