Proposition: since there is no "rules" property in activity pub I would just append the rules section with a "Rules" header to the summary in the activity pub representation. It is not the same as being on the same instance, but it is better than loosing this information

I was thinking of grabbing this one while I try to fix the lack of markdown/source/federation of styling (line breaks) for magazine descriptions unless you already have it in progress

I have not. Go for it 👍
