ICANN recently had some choice words [1] about blockchain DNS systems like Handshake and ENS.

I disagree with your statement in its entirety. The article I linked specifically argued that registrars absolutely make it clear.
From the article:
> When you go to a registrar's website and hover over such names or look for a disclaimer, it generally says something like "these domain names are not yet compatible with most traditional DNS systems."
> The term "yet" may be misleading to Internet users.
Their argument is that it's not absolutely clear.
