Your list of 'serious problems' mostly seem to be social issues, i.e. 1) It has no current users. 2) Developer preference for what you call 'power languages'

Your list of 'serious problems' mostly seem to be social issues, i.e. 1) It has no current users. 2) Developer preference for what you call 'power languages' as opposed to HTML5/Javascript. My retort: 1) Google launched behind a hord of other search engines like Lycos, Excite etc, but they conquered the search market. They simply did search better. 2) Show the data. The fact that the existing platforms imposed certain languages on developers doesn't mean that developers would voluntarily work in them if they had an option. Cordova/Phonegap seems to be a counter point to your claim.
