Thanks for your reply Anne. I understand how http: provides the added security level based on the assumption that the user is capable of making an informed decision based on the origin of the web application. 

When I refer to a more general model for allowing access to sensitive APIs I can for example mention that we are implementing a model for "Trusted Hosted Web Applications" in FFOS. The model is based on a signed certificate containing CSP definitions and list of permissions as well as secure transport and certificate pinning. This is probably too much for Geolocation but could be applicable for more sensitive APIs such as SysApps TCP and UDP Socket API or a powerful Media Storage API. See slide 6-8 in 
http://lists.w3.org/Archives/Public/public-sysapps/2014Sep/att-0000/SoMC_FFOS_Trusted_Hosted_Apps.pdf.
