I want to second this specifically with regard to XML and JSON. I
understand the concern about implicit casts to text, but what about
bundling with a built-in domain that pseudo-text types can be implicitly
cast to? Something like a generaltext type, where casts from other
pseudo-text types are implicitly cast?

hmmm might be worth playing around with this in extension format.....
