Just wanted to remind everyone that we control the whole stack, the
swift compiler, the package manager etc.  If something needs to change
in the tooling to pass extra arguments to the compiler to support this
feature, we can coordinate across all projects and make it happen.
Let's figure out an end state that we like, and that is feasible to
implement.
