My understanding of policy, in my own words, is that
- generated stuff must be possible to regenerate with software in
  debian main
- and should be regenerated during package build

So as long as we can regenerate the parsers, this is no policy
violation, but ideally we would actually do so during package build.

Please go ahead with bug reports and patches/commits for the affected
packages :)


Cheers,
