From what I have just read (again) - scope seems to be a way to indicate
the interface used (e.g., eth0, or enp0s25) as a "number".

Further, getsockname() (and getpeername()) seem to be more for after a
fork(), or perhaps after a pthread_create(). What remains unclear is why
would I ever care what the scopeid is.  Is it because it is "shiney",
does it add security (if so, how)?

And, as this has been added - what breaks in Python when "scopeid" is
not available?

I am thinking, if adding a scopeid is a way to assign an IPv6 address to
an interface - what is to prevent abuse? Why would I even want the same
(link-local IP address on eth0 and eth1 at the same time? Assuming that
it what it is making possible - the same IPv6/64 address on multiple
interfaces and use scope ID to be more selective/aware. It this an
alternative way to multiplex interfaces - now in the IP layer rather
than in the LAN layer?

If I understand why this is needed I may be able to come up with a way
to "get it working" for the Python model of interfaces - although,
probably not "fast".
