As it stands my understanding is that it is meant for all.
And by that i include the many newcomers to "Arduino" who would probably quit if they had to start and learn VS etc.
For those much more advanced they already have better tools than either CREATE or the desktop IDE and in most cases can run them without much problem.
Its not a case of "How advanced can they make it" its how easy can they make it for transition from the regular IDE and still keep it simple.
As you yourself say it fits that bill just fine although there are more bits seeming to get added each week whether it be a tweak or and addition.
AM sure the dev team will take your thoughts onboard but there is quite the list of things to be done to it yet already.
