Join desktop and web database into a single solution that renders HTML5 user interface
When database is created it should be possible to use it as a desktop database or to publish it onto for example IIS for a web usage without any changes to it. The publishing engine should be capable of rendering forms as a HTML5 user interface. VBA functionality should be interpreted as server side and or client side VB Script. Probaly forms should be saved as XML for that purpose.
I'm not sure how practical this really is, but if you go this route you might as well have Access build a Progressive Web App (PWA) that can run on anything.

@Kent - Applications built with Access are primarily used as in-facing apps by employees. It's too big of a security risk to allow anonymous users, and perhaps the primary reason MSFT deprecated public access to Sharepoint/AWA. There are other tools better suited for anonymous users, such LAMP stacks.
As to the OP's idea, Access Desktop could be used with REST as a RESTful server. VFP (VisualFoxPro) has successfully provided this capability!

What kinda like RDP?
Well you can do this now with an Azure VM running windows server but I've yet to figure out how to offer anonymous access.
