How are you even supposed to do do "horde" dungeons without, especially ragefire chasm, and stockades for the horde players, I don't find it worthwhile to go there at all, but it is fun to do it at their appropriate levels.
I don't see anything wrong with having it enables. yes yes "walking to the dungeon" part of the experience, I get that, but as also already mentioned, that takes a crapload of time and it will only work early on where people DO want to spend that time doing just that, but after a while (especially after a lot are 60 and then 70) 4 people will be heavily crippled if 1 decided to leave to a far away dungeon, having lost a crapload of time for nothing.
I know people dont like the feature at all even in wotlk, and on that I semi agree, but it is a good tool...
but most likely it will never be deplyoed since the majority do seem to hate it with burning passion
