or any of the 1.16 category extensions? Is the reason why it's not allowed because it isnt offered to all versions? and for something to be allowed that is similar to optifine have to be available to all versions?

Well yes you're correct. The initial kb is because of the cactus, but the lag amplifies it. Because it is so unreliable to get it, you can't really call this a strat. I see no reason why the run should be called glitched if this happens.
