One Pocket, Multiple Linked Entrances

Personal Pocket, but strip the player-specific definition to the pocket itself, being enter from any door with said id, but return the player to THEIR entrance door of which they entered FROM

the tree being similar to
OW1 > Global Pocket 0 > OW1

OW2 > Global Pocket 0 > OW2

OW3 > Global Pocket 0 > OW3

Regardless of the player, the entrance would lead to the same pocket, but always exit to the door they entered from.

This really seems like a when you code it issue

You are actually thinking too small with this idea. You could faction or even guild shared pockets or locations.
