Dealing with binning is fairly easy... I have something already done for
that one, but I'm not sure that it would be the best option.
My solution makes use of opp-supported-hw by "standard means", but perhaps
let's have a separated conversation about it?

I don't think that skipping this would give any benefit though, because
that is only adding a compatible and whatever binning support would have
to be generic and 99% not bound to any mediatek specific compatible.
