Yes it's a pain sometimes, I'd concede that. I have the schwalbe levers and they have worked up to now, but it is usually a good 5-10min fight. But if the hole won't fix and it'd need a boot, you'd have to take the tyre off anyway, so I think that's just a hazard of running tubeless generally
You could also choose to take anchovies, they hardly take up any space. Seems to me then you'd have more or less all bases covered
I go the other way - I take the same kit as if I was running tubes; I've had 2 non-sealed tubeless punctures before and wouldn't want to risk it otherwise. And if I'm taking a tube anyway, then no need to take any other extra bits as it either seals or I chuck a tube in it, as normal.
