As someone who is a little clueless about network infrastructure: if I own "dwrodri.com", and I'm not running a bunch of other services which need to point to this domain, is there any reason why I wouldn't have my root domain pointed to my personal website?

I would personally imagine that any individual or SOHO business hosting their website on GitHub/GitLab would just buy "MomAndPopShop.com" and point it there. I guess I don't know off the top of my head how many of those sorts of places on the web still exist...

The problem is not that they're pointing their apex domain to a personal website; the problem is that they have a CNAME record in place for their apex domain, which is not actually allowed per the DNS standards
