Not an uncommon thing at all. I've seen a lot of mowers where that is standard equipment, Snappers, Ariens Zero Turns etc. Putting rubber down is good too but the problem there is you get sand and stuff under it and after time it tends to sand the paint off and cause rust. You sound like you may be the guy who would clean it after every mowing but I think it still would rub off after time. The anti slip strips would stay in place till you peeled them off.
