should it be
$.definitions.LdapsSettings.pfxCertificate ?

[BethanyZhou]

Yes. $.definitions..pfxCertificate means $.definitions.*.pfxCertificate. It works as well.

seems like two cmdlet are renamed without alias, can you please confirm

[BethanyZhou]

Yes. Renaming these two cmdlets without alias is expected. Renamed 'New-AzADDomainServiceForestTrust'->'New-AzADDomainServiceForestTrustObject and 'New-AzADDomainServiceReplicaSet' -> 'New-AzADDomainServiceReplicaSetObject' to align with our naming convention. And Az.ADDomainService is under preview. I guess these changes should be fine.
