Indeed. And I didn't mean to imply anything else.

>> He insisteth that she go.
>> *He insisteth that she goeth.

Agreed. I understand the first is more formal.

Early literary Modern English sometimes helps us
with Old Norse where colloquial 21st century
Modern English doesn't.

In the first NC lesson, for example, I took some
phrases from the KJV of the Bible. "I am he who liveth." etc.

If I ever get to the point of writing a NC lesson
introducing the subjunctive I'll certainly start with
some subjunctive examples from English.

Anway, the point here was that only the first of the two
following sentences are correct Icelandic.

Hann vill at hon fari.
*Hann vill at hon ferr.
