Yes, this is the position I support.

Even I do not expect to kill SLs in the sense that we would reallocate
those addresses for other purposes, forbid using them under all 
conditions, expect routers to always filter them or hosts to always
ignore them, etc.   I don't like pulling the rug out from under
people who have built designs around them, even if I think their
designs are shortsighted and/or naive.  

I do however think we need to discourage use of SLs except in isolated
networks.  

I also think we need to make it clear that in general applications 
aren't expected to work in the presence of a mixture of scoped and 
global addresses.  Applications should treat SLs exactly like global
addresses. 

Finally I think we need to discourage the idea that SLs are a security
mechanism, because SL filters are at best only marginally better than
other kinds of address filters (and I'm being charitable there).
