It's not a recent change AFAIK, but nowadays dpkg is removing
entries of purged packages from the status file so maybe it's more
likely to happen than before due to this.

We recently documented that behaviour in dpkg-query however.

EXIT STATUS
       0      The requested query was successfully performed.

       1      Problems were encountered while parsing the command line or
              performing the query, including no file or package being found
              (except for --control-path).

You should consider an error like an indication that the package
is not installed.
