How would an optional, official parser be toxic?

You misunderstand what a gatekeeper is.

No, i get it, but you are doing the classic error of assuming it is "simple." It's going to have to be hard enough to be a decent gatekeeper. That means a lot of people will struggle with it, more than you think. The danger is that it takes long enough that it makes it harder for people to get involved in the tier. Ask a ffxi vet how long it took them to beat ma'at, for example.
