Will removing parameter --disable-workload-identity directly have a great impact on users?
If so, can we consider using c.deprecate(hide=True) to hide this parameter first? When most users migrate to parameter --enable-workload-identity False, then we remove it completely, so as to avoid big breaking change.

@zhoxing-ms

Thanks for the concern. Removing these flags won't impact current user as in AKS, this feature is not being enabled yet, only a small group of testers have access to it. So, removing it won't cause breaking change.
