Yes the difference is there. But if you're giving a special significance to the dildo, be prepared for the jurisprudence to be twisted into something you very much don't want.
It does say it's valid, but also that it's obsolete, and while the RFC does define valid but obsolete specs, there is nothing defining domains without a dot as obsolete, and it is in fact defined in the regular spec, not the obsolete section
1*atext meaning at least 1 alphanumeric character, followed by *("." 1*atext) meaning at least 0 "." 1*atext
If tomorrow, google decided to use its google top-level domain as an email domain, it would be perfectly valid, as could any other company owning top-level domains
Google even owns a gmail TLD so I wouldn't even be surprised if they decided to use it
Honestly I literally use it as a google replacement. Idk what happened with google but I just can't get anything useful out of it at all, and so I'll just ask ChatGPT to search online for stuff if google proves useless.
The only other use I like for it is learning new languages, as a developer it can help a lot, as long as it doesn't make shit up, which it does fairly regularly tbh
I used to do this a lot with google, but now that it's barely functioning at giving me correct results... Yeah I use chatgpt a lot. I'd love it if there was a functioning search engine instead, but there isn't
