I think there should an option which allows both players to abandon
the game, should they both wish and agree to.

Is that not a draw?

he means without impact on ratings and statistics, unlike a draw. I am
not in favour of the idea. It can complicate matters and would require
rules, in tournaments for instance. sin

Yes, but if you are going on holiday for example, or if you are going
to be away for a while, you don't want to time out all your games.

If you would like this option in order to experiment with sequences,
couldn't you just play an unrated game?
