I only got into Pathfinder 2e in the last six months or so. I enjoy it a lot, to be honest, though I don't have deep system mastery or even wide play experience.
My impression is that Pathfinder 2 is doing sufficiently well, though not quite as well when Pathfinder 1 came out and just dominated the D&D market for years. There's a couple of measures for that, but one thing I thought telling is the sort of missing support from OGL publishers who've historically strongly supported Pathfinder during 1e. E.g. Kobold Press. I recently took a look at their Midgard World Book and would have bought it, but then realized that Kobold Press isn't supporting Pathfinder 2. Don't know why, maybe they're just in a wait and see position. I have no idea. I do suspect, however, that if Pathfinder 2 had a large enough OGL market, then publishers like Kobold Press would jump to support it. Same for other big OGL supporters of Paizo back during its 1e era, e.g. Necromancer / Frog God Games.
So, I don't know. I honestly think there's plenty of support for this game out there, but the disparity of support from traditional OGL heavy weights is a bit of a downer.
Finally, to answer OP's question: no, it's not time for an Essentials reboot. What killed 4e at that point in time was the bi- or tri-furcation of a working product line into 3 sub-products, Red Box, Essentials, and 4.0 (including the mangling of 4.0 classes like the cleric by rolling out retroactive errata for Player's Handbook 1 etc., so slowly killing off 4.0 to better sell of Essentials classes). It's a pretty terrible sales approach that requires certain parameters that applied back in 3E, to some extent, but hasn't applied since. Also, in 4.0. you had a very consistent complexity level across most classes and so a simplified, easy-access mode / product-line was needed. You don't have that in PF 2 where some classes are extremely straight forward to build, being available to the entry level player.
So, no it's not time for Essentials PF 2. I would appreciate people posting more hacks / houserules if they want to do that. I loved Greywulf's 4e hack, he's the creator of Microlite 20, and his variant on 4e always struck me as ingenious. So yes, I'd love to see fan initiatives, but I don't want to see a reboot from the publisher.
