Personally, my issue with this is that it reduces the Doctor in a way, in a very important way.
The Doctor is the name they chose, he said it is a promise. That said everything about how they are, they made a choice about the person they wanted to be and that made them special, maybe even unique in all of space and time.
But nah, turns out that’s not what made them special, they were born that way and the most powerful race that ever existed with all its history and splendor is now just a pale copy of this anomaly.
I’m not going to lose any sleep over it. I’m also not going to be convinced to easily embrace it.
