It is clear to everyone that all it would change is the *output* of GHCi's :info and Haddock-generated docs, right? There's no change whatsoever to what programs are accepted by GHC, or what they mean. Yes that’s right. (Your patch was helpful in clarifying that.)
To me it doesn’t seem a big deal either way. Personally I’m on the fence on this one, but it’s true that we never do anything in a patch release except fix bugs, and Simon M was reluctant to break that policy without pretty strong reason. If there was an uprising of user sentiment that we ought to break that policy on this occasion, it’d be easily to do.

We typically do not do that. And the same would be true of 7.8.5.
