Saying "we'll let you cheat if you put a dedicated sound person on your team" is not the way to get more roles for sound designers and composers, plus we'd need to make sure said "sound designers" aren't also doing art, programming, writing or anything else to stop people just claiming "my secondary programmer is actually a composer because they put 1 single piano note in the game files". Not to mention how it would bring up arguments for why other roles should be counted separately, snowballing into teams of 5-6 people making things completely unfair on solo devs. Anyone who works directly on your game is a team member. Every team member is a further advantage over smaller teams and solo developers. The only reason teams are allowed at-all is to give people the option to get other people in to fill their own gaps in skill/knowledge, and if someone decides to waste one of those team slots on a 2nd programmer or something instead of a sound designer, that's on them.
