There is absolutely zero point to this distribution. If there is, the author fails to describe it. Why do we need a distribution that depends on "everything"? If something wants to install all of cpan, they might as well download the PAUSE index files and iterate through them themselves.
The cpantesters infrastructure is being wasted on this distribution, testing all its dependencies (all of CPAN!) needlessly, potentially obliterating any more nuanced testing that might have been done for these distributions individually.
This distribution should either be deleted immediately, or at least the documentation should be amended to explain what this distribution's purpose is.
