p.s. I guess par matters for Stableford scoring, so leave it on the scorecard or eliminate that game.
In strokeplay and matchplay the par of any hole is meaningless. It could easily be done away with and no-one would notice.
In Stableford and Bogey scoring however, it is intrinsic. Stableford is an extremely popular format among handicap golfers, as it is seen as more forgiving of the occasional "blow-up" hole.
If par was abolished we would need to invent a modified form of strokeplay to replace Stableford.
Maybe something along the lines of only your best 15 holes out of 18 actually counting, with a commensurate handicap adjustment ?
