Inui [comrade/them]

The Bazzite devs all use and suggest Lutris themselves for anything that isn’t Epic, and none of them use Bottles. I have no opinion and also use Lutris, but if OP wants help from them officially, that’s gonna be their suggestion.

They have a list of dates on their FAQ for different devices. It sounds like you may get a few more years beyond whenGoogle cuts off official support. https://grapheneos.org/faq#device-lifetime
