You are in no way forced to level 4 (6) allied races to 110, it's a choice.
There is a reason it is not given for free upon creation, it's supposed to be somewhat meaningful, yet 100% cosmetic.
In MMOs there's supposed to be content outside of end game grind, and that's where leveling and exploring the world while you immerse with your character comes in.
What's next? Introduce an "I win button" that gives you BIS? I mean, you can just choose not to use it, amirite?

Yeah that's where the confusion came from

100% agree - I'm super thrilled to level another character, however as I already got a 110 of each class, I'm waiting for the new allied races before throwing myself at it. But I've definitely been tempted to explore zones and their stories that I previously haven't.
