Creating in house wrappers for desktop and mobile would require an immense amount of work. It might be possible for Ashley to do it -- especially if he decided to fork some of the extant export options into C2 specific versions -- but it would mean all other new features grinding to a halt.
He's said as much before, and it's true.
Let's face it: shiny new features might not be as important to hardcore users as stability, better UI/workflow, and better export options...but Scirra's target markets (those who want to make a good looking game with minimal programming) are much more likely to care about shaders and shadows.
It is no point having shiny new features if the end product can't be reliably shipped to your intended platform, even those who are not hardcore users will want friends to play their created work.
As shinkan noted it is not our responsibility to lobby third party devs to fix bugs with exporters or pay someone else to do so, that responsibility lies solely with the developers of C2.
I for one have no problem with some kind of subscription payment model, not if it means getting rid of crappy third party components.
You simply can't keep passing the buck - if you do, the hardcore users will jump ship, and the above scenario of possible history outcomes for C2 may indeed be Que sara sera.....
