Well since Scirra supports Ejecta, the under iOS 8 is actually supported for now (if it does not work, report bugs correctly to see if they will fix it), even without ejecta, C2 games still work on iOS (through the safari webbrowser, you may think it is kind of a cheap justification, but actually the direct html5 export is the only one that produce a single result that runs everywhere without needed this stupid "build for each platform individually"), so their statement on the front page is true and accurate, as for cocoonJS, they should not take them back, ludei has to talk to scirra so they can offer good support, but we should remember that scirra has no means to guarantee that canvas+ will not break once again (as this is not their job to program canvas+, remember the people that complained to scirra directly rather than to ludei for some cocoonJS bugs? No wonder they did not get fixed, even ludei could not keep track of them).
PS: the html5 exports is known to be one of the thing ludei wants to support (it currently works?), so in the mid term the cocoonJS exporter itself should not even be nessecery, and the plugin is maintained by the community, as long as there is communication, it is good.
To be fair, the phonegap, ejecta, node webkit, etc... support should not really be a part of the built-in C2, and the same goes for cocoonJS, it is just convinient to have them, but none should be contractually quoted as exporters, dropping cocoonJS is just a part of what should have been done IMO.
