I do think that the work needed to actually support fractional precedence in ghc is pretty minimal. Or at least I remember having a conversation about it a few years ago, and the conclusion was that adding precedence would be super easy to do, but just lacked any good motivating example from real libraries.
I remember this discussion, too, and I guess that it was started by Simon Marlow and it ended with recalling that decades ago something more advanced was discussed: Groups of equal precedence and relations between the groups. But that one was too complicated to be implemented.
