Paizo might just be big enough for Pathfinder to matter, but never if they are determined to go independent of D&D. Then they are relegating themselves to be yet another Dungeon World, Savage Worlds, 13th Age, Swords & Wizardry, Tunnels & Trolls, MERP, HARP, DJ/Mythus, Numenera... or any other out of literally thousands of small-time hopefuls that all have faded into obscurity.
Nothing wrong with any of these games, except none of them support a corporation the size of Paizo. I would think Paizo's output is easily ten times bigger than any one of these bit players. Most of them have never even published ONE module with the gloss and finish of a Pathfinder module.
The only approach that can salvage Paizo's place as the #2 of level-and-class based fantasy ttrpgs is to do what Paizo did back in the era of 3E: offer "5E but better than 5E".
The only approach that allows you to keep buying Golarion goodness in any quantity and quality is if Paizo completely guts the existing playtest and completely reverse course.
Sorry if that feels harsh, but them's the breaks.
