Right, but we're talking about issues with backporting patches. We catch
a lot of issues where a patch applied to an older version, but is
missing stuff or is outright incorrect by having the compiler warn us
about it.

We're not trying to debug upstream, but rather to catch broken backports
that compile but are broken.

The value here is to make other errors obvious.
