I like all of these opinions/ideas and I also don't mind having BMX in the offroad class.
I've been following this conversation with interest. I'm not too invested in the definition of an offroad tire; there are various versions of offroad tires. There is also a fair amount of overlap, for instance the early 'knobby' style klunker tires were/are basic cruiser tires until purpose built knobbies came along. I like to run this style of cruiser tire on my vintage style klunker builds:

I built up this Redline for the last ORBO (still not finished quite how I want it). It has semi knobby tires which I think are designed for bike park riding. But I also live in the Sierra and these tires work fine for the dirt roads and trails around here, especially for an occasional use bike.

Question, would there be enough builds for a BMX specific class? I kind of doubt I'll do another BMX bike. I built this one to replace my high school bike that had been stolen many years ago. I'd like to collect a few more but I like the 'old school' era BMX bikes which are the most collectible and very, very pricey around here, so that's probably not going to happen. I might pick up some projects to fix up for donation bikes, so that's a possibility.
I could easily fall down the old school BMX rabbit hole though. Here's some that I love:
This is an '83 Redline very similar to my original. I had to use a '92 frame for my repro due to cost issues.
