Main City Aetheryte (World Transfer feature)

Hi Creative business unit III or Yoshi-P

I am writing this thread to asking whether if it's possible to have all the other main city Aetheryte have the world transfer function (Foundation, Kugane, Crystarium and Old Sharlayan) in 7.x or beyond? Also is there a reason for only the current 3 main cities (Ul'dah, Gridania and Limsa Lominsa) to have the world transfer function only? The reason I'm asking whether the other main cities can have this added feature is because I believe it can make it more convenient for players to transfer between worlds in a data center. If it's not possible due to T&C or policies then, please disregard this message.

Thank you for reading :)

Indeed, it would be a most welcome change.

Currently the three primary cities are heavily favored as home or free-teleport points due to their inter-world travel function.
Say I'm in Old Sharlayan and wish to join another world's hunt train starting in Labyrinthos, I have to first travel to Limsa (etc), transfer worlds, and then go back to Sharlayan.
It's impractical, and thus the likes of Limsa becomes the 'main hangout city' because that's where our free travel point is set.

It's a shame to have these wonderful new city hubs every new expansion that seem to almost never get used, outside of hastily popping in to spend tomes and nuts.
