Comment (by mf2k):

 Please review the expectations of a maintainer.
 https://guide.macports.org/chunked/project.contributing.html. Particularly
 section 7.3.3. Basically the whole point of a maintainer is so that we
 have people who can be assigned Trac tickets. If you don't want to be
 assigned tickets, we can remove you as a maintainer for your ports.
