But to know which plugin supports which gameid we would still need to
load all plugins? I don't really see how that would be faster than using
cached plugin mode in the first place (note that even for cached plugin
mode it will unload all except the one it actually needs when running a
game, so memory usage is only higher in the launcher/detection compared
