jean has not always been the phoenix itself and while she may have merged with it by the end of endsong, this doesn't retcon the original explanation of the DP saga - that the power was all hers - back into continuity. clearly, the phoenix exists by itself, independent of jean and and JG herself has not always manifested the PF, even if one might claim she's had a lingering connection to it.
The Phoenix Force made it's debut in comics with Jean Grey and thus was called the Phoenix after that in every back issue regarding a once nameless non-sentient force, as I tried to explain before the use of the name in retrospect is for the sake of the reader, why not continue to call it what it is after it's first appearance? When it hosted that Shi'ar it was not called Phoenix it was called Phalkon and Feron and company first referred to it as a celestial elemental or something like that. None of this makes it and Jean being the same any less true. The very nature of the White Hot Room explains how a mutant can be one and the same with a force that is older than the universe, you are always there waiting for yourself to arrive, this is a realm that is outside of time and space, the nexus of all realties, Jean is a piece of the whole, she is it's body when she is in the mortal coil, her blood can give you it's power, her genes can cause you to inherit it's power.
I give no argument that it is not independent of her, she was born billions of years later, yet she was always connected to it even before the shuttle, it had been a part of her, an aspect of her that reached out to Scott when he was in the orphanage was an adult Jean surrounded by the raptor and flame. The Phoenix has always been a part of Jean Grey and Jean has always been a part of the Phoenix in no way means that the Phoenix was created by Jean. It means Jean was created to be it's body, the house where it lives and was just as much a missing piece during Endsong as the rogue piece that thought it needed Scotts power to heal. It was hurt and confused and it went to find Jean, Rachel was on Earth if all it needed was a host (and she was another of it's favs "the Phoenix likes me remember"😉 she would have been sufficient, but she wasn't. why because the longing and confusion that piece felt was from Jean, that's why it thought it needed Scott, until Jean came and let it know otherwise. And like I said the White Phoenix merge happened in HCT before Endsong, and before this Jean was already White Phoenix after the suicide of DP, she was shown in the center of creation creating afterlives for the beings DP killed, which adds more credence to the whole Jean is Phoenix, Phoenix is Jean and the you are always there waiting for yourself to arrive. At least four times in different points in Xmen history Jean has been shown in the afterlife as White Phoenix.
