>For key rotation, it may not be as simple as it sounds. I expect better from MS as well but for example, for on-prem AD, the krbtgt account should be rotated yearly but in practice, it carries a huge risk of outages for accounts that depend on it a lot for kerberos ticketing.
If only there were internal development resources that Microsoft could leverage to build a more robust system, maybe one that allows for phasing in of new keys, and not have to wait on external vendors to get around to improving security like the rest of us do.
