Maybe it does, but it doesn't answer my question - to what problem is
this a solution? Also how is it expected to play out in practice? What
will the new security dialogs look like and will they baffle users
like all the others do? Has anyone already implemented it?

The list of 'legacy schemes' is a red flag for me. By what criteria is
inclusion in the list determined? Suppose the list needs to be
changed, does that require a change to the HTML specification? What is
it about 'mailto', really, that causes it to be treated differently
from 'http'? The word 'core' doesn't explain much to me.

A more conservative design would be to have a single new web: URI
scheme with a subscheme registry (sort of link urn:), rather than lots
of new URI schemes. This wouldn't allow registering behavior for
mailto:, but might mean fewer surprises and less standards innovation.

Not opposed, just confused. Someone has thought about this a lot, and
I don't know what they've thought.
