They haven't done their due diligence: there's already a well-known language named R: https://www.r-project.org/. The prime isn't sufficient disambiguation.
I assume they know but don't care. Either way, that is a bad choice. I think "Rad" would be a good name, but maybe they already are using that for something else.
I assumed R and R' are prototypical bootstrapping variants of what will be the full-fledged Radiant language, but that wasn't explicitly written anywhere.
