I did that for years and I recommend it as well. Pure linux desktop + console for games is a nice combo and a good separation of functions.
Of course... at this point I am back to having a PC with a beastly GPU and I boot Windows for games and CAD. It is hard to resist high framerate 4k gaming once it becomes a possibility, so now I need to figure out the secure boot problem for the occasional game that requires it.
I don't personally have a problem with a system being locked down in general. I have a problem with my computer being locked down, or getting rootkits installed on it. So for me at least, playing those games on console is a good solution.
That's the seperation of concerns that drives me to a Switch alongside my computer. Though I'm by no means a "serious" gamer by most people's standards.
I still play on my ps2 ... because consoles are linked closely to the games of that generation I would guess that they are tech that are on relative terms least discarded
