I agree with @DenialOfNature
It should not be another variant, it's no bonus for good play either. We are debating whether a rule in chess is accurate and benefits the game or is illogical and inconsistent. If the rules are illogical and inconsistent, the quality of the game decreases. In snakes and ladders, a certain ratio of snakes to ladders is chosen such that the game is most enjoyable, fun and not too long. That's what we're doing here.
Current rule is accurate, benefits the game, and is completely logical and consistent. I dont see any problems.
But it could 100% be a variant though.
DRAW.
VARIANT.
Of course you're talking about a variant, since most players won't consider it.
The rules as they are are neither illogical nor inconsistent, except that they may be inconsistent with your own wishes. No argument has been presented here as to why the present rules are illogical, so we're discussing a variant.
