That's the point of the Supporter package. It makes functions of BB easier, but doesn't provide advantages to be used in a game.
For example, Supporters can be alerted via e-mail or text five minutes before a TL auction is about to end - but non-supporters can set an alarm on their phone manually.
The line is drawn clearly and perfectly, and I see no reason why Supporters shouldn't suggest more features, if they do in fact make the package more enticing. Any suggestion by a Supporter looking for an in-game advantage in the Support package will not be implemented. Why are you concerned?
