I'd prefer we don't split into separate diagnostics; that increases overhead
and maintenance burden for very little gain IMO. We generally prefer using
`%select` when possible (it makes it easier to reword diagnostics, fix typos,
localize, etc and it avoids adding extra strings to the binary when string
merging isn't possible).
