To be clear, I'm not against forwarding `kwargs`. The minimum is to have a link pointing directly at the place it's forwarded to. Slightly better is to also explicitly write out the useful ones which are forwarded. Even better is not to have `kwargs`.

I encountered this just the other day with dragon where we had to go to something like five places in the code to find out what arguments were possible and what they meant because none of the forwarders documented what were sensible arguments or where to find them.
