Heh. indeed.

I would have thought so, but AFAIK, most folks who write one-off
transformations use clang-tidy, rather than writing a standalone tool. They
just ignore the diagnostics, i gather. Transformer may shift that somewhat if
we improve the experience of writing a (throwaway) standalone tool, but for the
time being I think we can't assume that.
