I'm not sure how to proceed with this: it causes a huge number of
warnings, because there are many packages still not fixed.

So, two options:

 (1) We merge this and live for warnings for the next few weeks until
 all packages are fixed. The advantage is that people will notice that
 packages need to be fixed.

 (2) We wait until all packages are fixed, and then we merge the
 check-package change to make sure we don't regress on this.

I'm not sure which is best. Perhaps we need to do (2) for a little
while in order to reduce the number of warnings, and then go for (1) ?
I'm not sure.

In any case, I'm also getting some weird Python exceptions while
running "make check-package":
