That's... interesting. I think it would make more sense for these
packages to state this dependency explicitly instead of relying on the
dep from the eclass.

This is incorrect; programs executed in pkg_postinst/pkg_postrm should
be present in RDEPEND. Consider a binpkg installation, which would
ignore DEPEND, but would still execute pkg_postinst.

Another option: since xdg-utils.eclass functions will politely skip
the updates if the tools are missing, we could just drop the
dependency from xdg.eclass entirely and wait for the tools to get
installed through some indirect means.
