I have no opinion whether it makes sense to spend time on updating this
DE that was long abandoned by upstream. IIRC someone suggested to remove
it a few years back.

Be that as it may: if a port has a maintainer, please Cc them whenever
you send a diff. You can simply ask them if they still want to be
maintainer. You might even get a reply indicating why they preferred not
to update the old version. If you don't get an answer or the mail
bounces you then have a good reason to remove them.
