URI::PackageURL as a Perl toolchain dependency?

[sjn]

Hei!

One of my wishlist items for the Perl Toolchain Summit this year, is to explore using PURLs as a way to both communicate resolved dependencies, and for specifying requirements (which should be possible once @pombredanne's version-range-spec branch is merge into purl-spec).

One likely consequence can be that this package becomes a whole lot more critical within the CPAN ecosystem since it might be placed waay up the CPAN dependency tree, with all the risks and responsibilities this entails.

If such a thing happens, would you be comfortable with this?
