While technically it is possible to register those, in practice you
would need to use a bunch of internal  APIs to properly implement any
of those externally, so its not really possible.
ffurl has been private forever now, and making it public would require
a proper documented, supported and stable API and ABI, which is not
something that should be taken lightly.

The URL API has not been public for years and years, so nothing really
changed for a long time, except the internal implementation of private
functionality.
There is an alternative to use avio, which is what will remain the
standard way to hook in custom IO functionality.
