I have an idea that could theoretically please everyone.
Throw is used to transfer the potion. The recipient still has to drink it. That's how potions work.
It can't miss since it's not an attack. The recipient always catches the potion or it could be an easy DC 5 Dex check. Fail the check and the potion breaks and is wasted. Some risk should be involved in throwing glass bottles around in combat.
This doesn't step on the toes of Healing Word because it still needs to be consumed by the new owner and cost their Bonus Action, and things can happen before they get a turn. And it just makes sense, while Larian's multi-use drinkable gas cloud bomb fun potions do not.
Of course this assumes that Magic Pockets would be disabled in combat or it would be pointless to transfer potions in any other way. Which should be since sharing items without any kind of action cost is ridiculous to begin with.
