Can we have a url flag to allow mobile browser usage

now that there are huge improvements to safari, can we have a way to tell to allow mobile browser usage? so my idea is on the URL there is a new parameter &allowbrowser=true and so when the page loads on a mobile it will allow it to run in the browser rather than force it to the app? We appreciate browser on mobile isn’t 100% ready, but this at least lets more of us test it. Sound feasible?
