No, but you can. It's your personal choice to go down that rabbit hole, and label things "required".
I can think of a single WA that is absolutely necessary for me in M+: an interrupt tracker. But even if I don't have it, I would still be able to play a non-shaman healer role at 3k+ score and try to be oblivious to how the rest of the group manage their interrupts. There are QoL WAs that I'm really used to, such as Nnogga's party
cooldown tracker or MDT. But losing them will not suddenly stop me from timing keys that I can time right now.
I have seen a top AWC player do hardcore PvE content with basically standard WoW UI. That was eye opening. You don't need 100 WAs to be good.
I did solo 5-mask clear of Orgrimmar without paying any attention to the Gift buff (I did not watch or read any guides, wanted to learn it on my own, so I just did not think I had to track any buffs). If I kept on failing, I would have a choice to either wait and try a couple of weeks later (causal approach), or to min-max the fuck out of it (like getting all WAs) and push for completing it now (hardcore approach). You don't have to choose the latter.
