[basic.compound] p3

an object of type T that is not an array element is considered to belong to an array with one element of type T.

Does it mean this rule also applies to any subobject that is not an array element? It does not make sense, I also think it's not the intent of the rule. The free room to construe this rule could result in #3614.

Could we rephrase it to that?

a complete object of type T is considered to be the initial element of an array with one element of type T.

If the intent isn't to make std::views::single(suboject) a valid range, where is the wording that would make it such?

Yes, you're right. That's the exact intent.
