The problem with switching repairing scvs to high priority is that this action could be abused by the terran.
For example you could have a flying damaged barracks with a bunch of scvs underneith it behind their army, when your army engages theirs they could set all their scvs to repair it and then all of a sudden your hydras and roaches stop engaging the terran army and start running by them to attack the scvs instead.

I don't think that's how it works. I'm saying treat scvs the same way as medivacs. I never see medivacs have this sort of issue (except maybe with mutas) so scvs shouldn't either. I've never seen units try to swing in to attack medivacs if they're in the back of the bioball.
No, that's not the issue. The issue IMO is that this makes repair significantly weaker and apparently that's not ok.
