In this case, though, the warning isn't a false positive. Here are the
release notes for 0.48.0 that relate to the argument in question:
https://github.com/mesonbuild/meson/blob/master/docs/markdown/Release-notes-for-0.48.0.md#new-kwarg-console-for-custom_target
I probably missed something.

Incidentally, I've dropped my own patch related to this from a series I
was developing to run tests on travis. I think it's a bit annoying that
we need the techboard to decide for cases like these, but I guess that's
just a fact of life.
