relinquish at some point to allow contributions coming more easily (not to
impose hard lock). These days, there is no reason to yield maintainership
with the more lax rules and general consensus that casual changes do not
necessarily require explicit approval from maintainer prior to commit.
On the other hand, unmaintained ports can give (arguably false) impression
of being unwanted and one step above deprecation, yet these ports are not.
