While I support the feature/properties work, it's unclear to me that it will
be long-term viable.  It might be, and I hope it is, but we just don't know
yet.  As well, while I do tend towards supporting abstractions that cover
all cases, often it just doesn't work out that way and the 80/20 solution is

I think an 80/20 point would be to at least be able to use some of the HTTP
header fields, like username/password.  Your assertion about "better"
asserts the 100/100 solution, and I think the 80/20 should be also looked
at.  So my counter is that if setting header fields work is to be done,
including username/password should be part of that.  How can that be a thing
not to do if you are already doing header fields?  Why exclude some headers?
I would have expected pushback from the complexity of modelling HTTP
challenge MEP in WSDL, but not this part.
