In other words, this mechanism suffers from the very same upgrade

Yup, what y'all said -- anyone can setup the test, but it won't generate
useful data until implemented in resolvers. Sentinal will generate much
more useful data (it's measuing what users will experiance, not what
resolvers will experiance), but still needs to be deployed -- I was
somewhat surprised by how quickly RFC8145 will deployed - I guess we need
a: this to be implmented, and then b: some security events to cuase
upgrades :-)

I ment to include the below in my original bloviation:
I think it would be really useful to reach out to the press who published
articles on the keyroll pause (e.g: BleepingComputer, Bloomberg, Modern
Ghana, The Register, ITWorld, etc) - having them be told ahead of time that
ICANN stopped things, got community feedback and is proceeding cautiously
(potentially) changes the narrative completely - and, at least, helps
prevent the bad PR hit to ICANN (this is an ICANN list, after all) and them
feeling blindsided. Converting the potential PR ding into a win would be
nice - and may also reach more people.
