And superseded means the latest "hot thing" is _fully_ implemented to
a production quality standard before the previous standard is considered
to no longer be the current standard. :-)

Although given how critical LLVM has become, and given what's involved
in compiling it, I would argue that we should in addition be at least
half-way to the _next_ standard before making that switch.

That means that by then most of the requirements should now be showing up
in the distributions. Remember that it's not just LLVM core that's involved
here but also all the add-on components as well.
