[dns-operations] A request for "data"

[Edward Lewis]

An open question...

Is anyone aware of any use of Automated Updates of DNS Trust Anchors, documented in RFC 5011, in the last 5 years or so?  Does anyone know of a zone (other than the root) that documents or publicizes a reliance on Automated Updates?

For the record, the last time a ccTLD published a revoked SEP key was April 9, 2019 (this was not the revocation of the root zone KSK but a TLD's KSK), so I know that none of the TLDs have completed an Automated Updates roll since then.

I have no historical data below the TLD level, so I'm seeking anecdotal evidence of reliance on Automated Updates anywhere (else) in the global public Internet.  I doubt there is any, but that is based on absolutely no data and personal assumptions.

Private replies are fine...I'm not trying to name operators, just evaluate the mechanism's adoption.
