I hear you, and fair enough, but I think the fact that none of these gaming-specific phones has physical controls like you described built in speaks to how impractical that ask is.
And I think it’s important to note: there’s weren’t just powerful phones (in fact, many of them seemed to get bested by other phones in more benchmarks than they won), they were specifically marketed and sold as gaming phones; that was the specific niche that Asus, Lenovo, Razer, and others all sought to fill. Despite that, and despite basically all those companies having a ton of general experience building gaming hardware of one sort or another, none of them thought it was a good idea to include physical input methods on-device. They pretty much all have accessories that turn it into something looking akin to a Switch or DS, but none had them baked into the actual phone.
And I honestly think that makes a lot of sense. Thumb sticks aren’t super pocket-able, and I feel like even if they could be made to fit into a pocket, sliding them in and out of bags and pants over and over would make them fail faster. And while A/B/X/Y buttons might be more reasonable on that pocket-ability metric, do you want to smush them (or thumb sticks, for that matter) against your face while you take a call?
While current controller-esque buttons and thumb sticks remain the primary input method for games, I really don’t see gaming phones including those input methods within their physical form factor. It might be a limitation of my imagination, but I just can’t envision how one would make that work (and it seems I am not alone in that).
That was a fun read, thank you.
