This is the current choice developers face - build for the app-store or build for the web. Or both.
For me, I honestly don't care if Mobile Safari seems 'crippled' when everything I use works exactly the same on devices as on Firefox/Desktop. If anything I'd be more annoyed if it worked better on my fringe devices, but maybe I'm the outlier here - I only use mobile for comms/banking, tablet for light browsing, and it's more often I'll be on Desktop.
Do I think it should have less functionality in Mobile Safari - yes if I get more battery life. Conversely no, if those features could give me more battery life back through intelligent apps.
