There is a nist-pages branch in OSCAL-Pages, but we are not using this since it will publish a site at https://pages.nist.gov/OSCAL-Pages. Since redirects are not supported, we cross push to the OSCAL repository directly.

I was going to write something else, but I understand what you mean and there was an interesting technical problem with that. This is a small and easy fix, we can prioritize this to be fixed soon. Thanks for the report, @OR13.
