there is something a bit like this, you have supported="partial" or "no"
however due to the nature of the lists and systems it's a lot more difficult to maintain, and not all lists have it hooked up.
one small change can potentially affect the working status of several thousand games, also console and computer games often combine more elements than arcade games meaning you're more often faced with situations where one part of a game works fine, but another doesn't because they're more ambitious titles.
for more mature drivers and lists it works well however.
sometimes for difficult cases where a specific machine is needed there are compatibility tags, or in cases where specific machine configurations are needed / loading methods are needed comments are left either in the softlist or in the driver (some of these might one day might gain optional lua automation if we can reference scripts and script fragments from the lists)
