Hi Rob,
IF the software library support keeps all the simpler existing Arduino commands, I don't think it's a problem.
IF the documentation has a nice subset for beginners, even better.
IF the Price Is Right then having features/capabilities that many don't use is not a problem.
Consider a Mega today, and the many, many contributed libraries. That has a lot more complexity than most people use. And few use a lot of it at once..
What's your opinion??
