[policy, no patch] Allow docblock to be removed when modifying constructor params

+1 Yes please! If we're changing the params, we would normally have to be updating the docs to match. In this case, removing the docs is better than "fixing" them.

+1 from me too, if it's in scope to add to the docblock, it's also in scope to remove it altogether given the new coding standard. I co-incidentally ran into this today on 📌 Use MessagesCommand in BigPipe to remove special casing of the messages placeholder Fixed and took the approach here.
