Sure, although it's always hard to know who needed them or not. For instance,
Ludovic Brenta apparently did not have the same requirements when he did
the packages for Debian.

Sure, or add exceptions in binding.xml.
The point is that unless you are using the exact same setup, we can't be
sure you are generating the same sources.

The patch has been included, by the way, although that doesn't change
the usefulness of this discussion.

Sounds like a plan indeed, so that you can check whether you are able
to generate those files (still not sure what added quality insurance that
gives you, but certainly fine for the final users).
