My point is exactly relevant to what you were refering. I say "it's limited", and it's not okay. You say "it's limited", but it's okay for you. Just because they started after others (and who has not?)
In my life I heard too much about how easy somebody can build new wings for the existing house. Everybody can do it. Only their competitors do decorations. Modular architecture, object-oriented architecture, component-based architecture, service-based architecture, blah-blah-blah. But I'd never seen a nuclear plant built from a living house, or a submarine built from a car. It's just a marketing, nothing more. But I see, they found a fertile field.
modo is cool, but it's not impossible to be a leader in one (even important) aspect. They already have a problem with render scalability (60% speed-up after doubling CPU quantity is not "linear" and not even "near linear"), they will encounter more and more difficulties as they will implement more and more features. As a result you will have just another tool good in some things and not so good (maybe even bad) in others.
