so you diesied to go exploring but you forgot to bring food and a bed to sleep in and a map so you try to fing home and got more lost well what if you could get home with out a map what if there was recall potions. in order to make these you need to make a eye of ender and awkward potion (recall potions are not crafable yet but hopefuly something to add in the next update please mojang)
It could work, but I'd have to agree that this seems a little overpowered. For me at least, part of the fun of exploring is the knowledge that you can wind up getting hopelessly lost if you don't bring the proper equipment- that if you lose all you're stuff, you're going to have to get all the way back there, preferably before it vanishes.
That being said, I don't think something like this could be implemented- just not in potion form. The Waystones mod, for example, allows players to build waystones that allow them to warp between other waystones, keeping the exploration aspect, while not necessitating lengthy back and forth trips or dangerous nether highways to get from place to place. Without a mechanic, I might argue that the incentives for exploration sort of outweigh the advantages of staying in one place.
