Existence of `xms_az_rid` field in activity logs of user assigned managed identity actions

Since the beginning of May (2023), we've started to see activity logs containing the field xms_az_rid , when the activity was made by a user assigned managed identity.

Before May, 0% of such logs contained that field.
Since May, ~90% of such logs contained that field.

We wanted to know:

  1. What kinds of activities generate a log without this field (for user assigned managed identities)?
  2. What caused this change?
