Projects can do this already. It's the reason we have licenses. The problem are people want to license under MIT, but want more than just recognition.
If you want to get paid, use the GPL, and offer dual licensing. It's that easy.
Oh, it's not "that" easy? So you are really just using MIT as a marketing tool until you get large enough where you can pull the rug out from under everyone and start demanding things?
The problem isn't open source. The problem is the expectation that the MIT license means more than it does. You got what you asked for.
