Would returning the actual URL for the package be in scope? Open to a PR for that?

[erwin]

For example, in the README.md you have:

purl = PackageURL.parse("pkg:gem/[email protected]")

Are you open to a function that returns? purl.url maybe?

https://rubygems.org/gems/rails/versions/6.1.4

Would need to handle for every possible package repo.

Maybe it's outside the scope of package-url's but sure would also be nice to programmatically capture the link for the canonical version of the source code, for example, https://github.com/rails/rails
