The alternative would be:

  - get rid of LIBFOO_REDISTRIBUTE
  - add LIBFOO_LEGAL_INFO = {IGNORE,LIST,FULL} (or whatever name/values).

Thomas, Peter and Luca were not very happy with such a tristate, and in

Not so sure... Such hooks are made to save extra stuff into legal-info,
or to prepare the package for legal-info. So, if the package is excluded
for legal-info, there is no reason to run those hooks to start with, is
there?
