Proposal to extend FieldPat in Template Haskell

(sorry for the repost, I forgot to add a subject.)
I was just doing some work with Template Haskell and I noticed that the AST
does not have support for record puns and wild-cards. I know that these
could be desugared into ordinary record patterns but I think that it would
be more convenient for users (and also more consistent with the rest of the
AST) if we provided direct support for them.
So I propose to change:
type FieldPat = (Name, Pat)
data FieldPat = RecordFileldP Name Pat -- x = P
| RecordPunP Name -- x
| RecordWildP -- ..
Would there be any objections to doing so? If not, I'd be happy to have a
go at making the change.
