I know, that's why I asked. I think this is the simplest way to deal with this type of error. I therefore prefer it.

The introspection endpoint uses the same pattern of a token= parameter, but since the whole point of the introspection endpoint is determining token validity it doesn't actually throw an error here.

I don't think we should create a bunch of specific error values that are endpoint specific and could overlap which is where the whole error return value started.

As I'm writing this out, I'm not convinced that it could, really, so this may be a bike shedding argument.
