Namespaces used: beneficial to test for?

Issue type: :question: Question

In working on #196, I checked all cases where the prefix-ns package was used and what the namespaces were taken from that package.

That resulted in the below list of prefixes and namespaces, that I cross-referenced with prefix.cc. Most are as expected, but some are not.

This is not unexpected as prefixes aren't meant to be truly unique. Would it be beneficial to write a PR for a Mocha test that checks the output of prefix-ns?

I made one but there's the issue that it would just check the hardcoded namespaces, where some are as-expected, some are not. A better solution to prevent something like #195 from happening again is to make a proper file that exports these prefixes, which are to be imported by the other JS files.

Would you be open for a PR doing just that -- or is there some use to prefix-ns that I missed?
