If Valve is working with Ayaneo to get SteamOS shipped on these devices, then I imagine Valve would have some level of involvement on at least the software support side, even for things specific to the device. If Ayaneo is just like shipping by using one of the existing 3rd party SteamOS installers and not working with Valve at all, then yeah I expect things to be not as smooth sailing as the Deck.
Doubt the price and support would be any helpful over Steam Decks
