I think period pieces in general. Even if the idea is mundane enough, it seems if you add "1960s" or "1980s" onto it it suddenly makes that mundane idea into a niche, obscure one. People are too afraid to research or deepen an idea with period flavor.

This is sadly pretty accurate. I think a lot of people genuinely do fear any historical RP's because it requires doing research. There's no harm in researching things. I mean, I just had to look up SS and Gestapo ranks for a RP I'm doing on another site that is set in Nazi Germany. It was actually kind of fun just for the sake of learning some things I hadn't known before.
