Not the Makefile.PL?

Because CPAN needs a canonical format that everybody can work with.
And with everybody I also mean people working with other tools than
perl.

Depends on which human you mean. The author of the XXX.PL file will
prefer to edit hist XXX.PL file. The user of module Foo will prefer to
read either the canonical format or the output of some tool which in
turn will read the canonical format. The author might prefer to not
even distribute his XXX.PL some day.
Storable as canonical format is absolutely no option because it has
had too many perl-version-specific bugs in the past and because it is
not available to other tools.
