DNSSec mess with SHA1

Hi Folks,

I just wonder what's your take is on the current DNSSec mess with SHA1?

There are still a lot of top level domains being signed with SHA1 and look like nobody really cares?
Current OS releases like RHEL9 and others simply removed SHA1 from the code so if you're running BIND with "dnssec-validation auto" all those domains fails to resolve and the only way is to "dnssec-validation no" which eliminated the whole idea of DNSSec!

The worst is that even nist.gov fails WFT!

Any advice or ideas?

Thank you,
Wolfgang
