Feed Validator HTTPS enclosure URL

Hello,

I’ve been working on modifying some RSS feeds per recent https requirements from iTunes and elsewhere. In doing so, I’ve noticed that the requirement from the RSS 2.0 specification that the “the url must be an http url” is being interpreted to exclude https. I would assume that https is a superset of http and thus included in this definition.

Assuming that this is a correct interpretation, what would be involved in fixing the validator to allow https urls in enclosures?

For reference, iTunes is going to require the enclosure URLs to be https before long, meaning that all iTunes Store compatible URLs will not validate: https://itunespartner.apple.com/en/podcasts/faq#76672088
