Not to mention that in the UK a basic PPL with no ratings can fly IFR, and
only needs a Night Qualification to fly at night. I understand that
elsewhere, any night flying (as here) is IFR, and IFR is not allowed without
a full IR.

Hence even night flying requires an IR outside the UK.

In the US, all you need is three takeoffs and landings at night within
the past 90 days to be qualified at night -- no IFR, "night rating," etc.
