If the user installs XFCE manually in the profile, I'm not sure it will
find locally installed plugins anyway will it? I haven't tested it. I
use XFCE installed globally via the service.

With XFCE in the local profile it is not possible for a login manager to
detect and launch it, so to use it with a login manager it must be
installed globally, just like on any other distro. I guess that is
acceptable.

Perhaps it is ok to let the user take responsibility for any such
incompatibility that may occur?
