It appears that the only problem here is to get the URI scheme 
registration into the system; any browser can do that already (at least 
during installation, otherwise it wouldn't handle "http").

So what remains is a policy question; do you *want* a web page to be 
able to register new scheme handlers?

Using a fixed prefix sidesteps the issue in that it creates a class of 
URI schemes that are easier to register for web services. What's totally 
unclear is what kind of schemes these would be, and why it would be OK 
for them to be "web" specific. I'm not saying there aren't any, but the 
spec doesn't provide any insight here. The example mentioned alongside 
with "mailto" is "web+auth", but I have no idea what this is.
