All of the current Linux phones have major showstopper issues, and saying we're complaining about them being "unable to run modern PC games" is a strawman. The simple fact of the matter is there are no decent mobile Linux options available.
The most endemic problem right now is "Linux" phones that use crummy forked vendor kernels and Halium. For all intents and purposes, these devices are trapped in time and can't meaningfully get software updates for major system components. The 2 decent Halium-free options, the Pinephone and the Librem 5, both still use downstream kernels, and the Pinephone's kernel is maintained by 1 person in their spare time. I think it's apparent that this is not sustainable, and one can't reasonably expect megi to maintain this device forever.
As sad as it makes me feel to say this, I don't foresee these problems improving for a long time. As of now, I remain stuck with a Moto E6 from 2019 (Android 9.0) as it seems to be the final device ever produced with a replaceable battery, headphone jack, SD card slot, and screws instead of glue.
