The mistake here is conflating PC gamers to console gamers. Whilst there will be some who game on both platforms, many like myself are primarily console gamers to avoid this sort of nonsense. It doesn't matter to most console gamers that better PC versions exist, that has and always will be the case to those who want to invest the money on the PC side. It will however affect console owners if they know a better version of their console exists, that runs games better, and takes development time and consideration away from their vanilla system, offers less value proposition going forward, and likely unnecessarily extends the life of the generation because of this incremental update.
I much prefer the idea of shorter generations, to longer ones with iterative hardware releases in-between. The PS4K is still going to be held back by the PS4, which makes it even less value for money.
