I feel like I know tons of people who do absolutely everything, boyslash femslash transfic het poly threesomes and so on
This has been my experience too. But the people I hang out with aren't a random sampling, and I tend to go for fandoms and tropes and then seek out femslash. Hmmm...and I can actually think of some people I know who seem to only make femslash exclusively, but they share the "people I know who make femslash" category in my brain with lots of people who also create het, slash, and gen.
For me "femslash fandom" is just a social grouping of people with a shared interest in femslash, in the same way that Homestuck fandom is a social grouping of people with a shared interest in Homestuck (which not everyone who likes Homestuck will be into). It's thus not mutually exclusive with being into het/slash etc. But I only really got heavily into making and sharing fanworks online around 5-7 years ago, which probably influences my perspective.
