Valve doesn't try to make general purpose engines, they make engines that suit their own games, so unless you happen to be making a game which is shaped very much like HL:Alyx or CS2 you would probably be underwhelmed with Source 2. That includes platform support, Source 2 doesn't officially support any of the consoles because Valve hasn't needed it to, having only ever shipped it on PC and (briefly) Android/iOS.
