Perhaps never, perhaps its because its the classic show which gives it that right alone. Just because the new show has been going almost as long as the old one and presumably will overtake it in the next few years isn't a justification on it own. Heck the first hints in Nu Who about the Timeless child were introduced in Jodie's second year back in 2020 with 'Fugitive of the Judoon' - 15 years since 'Rose' was broadcast. I certainly think current Who is in a mess with fundamental changes bombastically introduced that cannot easily be ignored nor undone. Had the produces of the classic show stuck to their guns about pre-Hartnell Doctors it probably would have just been that, a few extra incarnations. But with Nu Who they had to jump the shark by elevating the Doctor to being the originator of regenerations, not be Gallifreyan and the abusive childhood they endured with their adoptive mother. I'm racking my brains to figure out ways without a reboot to walk back the Timeless Child/Fugitive Doctor, which I'm sorry has fundamentally changed the character and the show (in my admittedly subjective opinion) for the worse. I pity the poor future show runner who tries to do just that with or without a reboot, partial or otherwise.
