American ETFs (e.g. ISIN : USxxxxx)

I have read some of the threads @SebReitz.
Examples being:

US Cannabis ETFs
Motley Fool US ETF additions - #2 by SebReitz

The only one with a real detailed comment is this one where Viktor provided an answer…

US domiciled ETFs - without the KIIDs? - #5 by damo

…but this answer, even though there seems to have been an update from Apr 2020, says it’s from 24 Aug 2018.

Is there a way to get a more definitive and up-to-date comment from someone like Viktor again?

This is important to me as I have quite a bit of my investments in ETFs and the IE ones are not well covered (or well discussed).

Thanks
