I require symmetric since I upload a lot, plus I am on videoconferences frequently. I'd personally rather go for 100/100 than gigabit/something less than 100.
DOCSIS 3.0 (I think that's the latest) allocates a particular ratio of download vs upload frequencies, so even when speeds increase the asymmetry is still the same. I heard the next version of DOCSIS might change that though. Ideally there'd be enough fiber to not require DOCSIS anyway, but I don't have my hopes up for that.
Hopefully with a lot more WFH arrangements people start demanding symmetric connections. But
