I understand but it is dated and doesn't answer my question.

11.28.18 "PRIIPs requires funds, so both active and passive, to provide a Key Information Document (KID). This KID enables investors to asses the risk, reward and costs in one swift read.
Since it’s a European regulation, European funds were ready by the time the new rules came into effect. without it, they wouldn’t be allowed to be public.
US-based ETFs didn’t bother to comply since their focus is the US so creating this EU approved documentation wasn’t and still isn’t a priority nor will it ever be.
As a result, brokers weren’t allowed to make the funds that didn’t offer a KID to their clients."
If it
ONLY a matter of filling out a form or creating something akin to a new prospectus it hard to understand that the sponsors of e.g. SPY wouldn't comply.
