The problem for me here seems to be uneven approaches to end states across
the codebase, which is kinda of what I was wondering about in laying out
those tasks. With nsIPrincipal, I have a BasePrincipal concrete(ish) class
to work with. When I was adding infallible SchemeIs via %{C++%} blocks to
nsIURI, that was about the only choice I had because nsIURI could directly
be nsStandardURI, nsSimpleURI, etc... As we wanting to move toward more
Base* (if abstract) C++ classes as the top level of interface work in C++
where possible?
