Those actions were taken today. I don't know if others were done in the past, as part of a larger rename effort (and that's the issue: not knowing).
Those two questions are about the MD-80. If the ultimate goal is erasing md-80 in favor of dc-9-family, I think it needs to go through a discussion here first via a request for synonyms to the dc-9-family.
Community consensus will help with future tags. For example, if someone tags boeing-717, should it automatically change to dc-9-family, or will this manual rename effort continue in the background without consensus?
To streamline the process:
► Should MD-80/-90 and Boeing 717 be synonyms to the dc-9-family or not, and why?
Note that in @fooot's answer to Were the MD-90 and 717 ever known by DC-9-9x names the following was proposed:
I think we should at least have separate tags for them.
