It seems that maintainership is regarded as a status symbol in MP: the guy who sleeps with this Portfile. That's strange. Anyone can improve a port, be it a typo or a fundamental fix.
Instead, it's supposed to be a responsibility. Out of all the people who can better this port for fun and profit, this guy actualy takes that on as a duty. (Presumably because he regularly uses the port, knows the insides, and cares whether it works as well as possible; he is personaly invested in it.) In that sense, "openmaintainer" means nothing: it means "I don't mind if you do my job for me". Implementing fine-grained levels of open-maintainership (with labels or Portfile declarations or whatever) sounds like a commitee-designed paperwork nightmare. (Am I actually allowed to propose this? Oh, it has "minorrevisions" in the tags. Is this a minor revision? I don't know?) Ditch all that. If you have an idea about a port, implement it (test it, etc) and propose it. It is the maintainers job then to deal with it.
