I agree on the design meeting stuff...if it was me, lighting, and director (and again, yes, often doesn't include SM), I'd keep track of some general stuff for my own notes, and if there was something of note, to put it in the rehearsal report for that day.
As for production meeting notes, I've found it really depends on the company (especially whether they have a status quo of always having them), as well as how many people really do show up at the meeting. If you plan a production meeting that's supposed to involve everyone, and only a third are able to actually come, then minutes are more crucial to keep everyone in the loop. Sometimes though in this case the production manager would disseminate them too.
But I wouldn't have done them for a lighting meeting (unless told ahead of time that was status quo).
