I think the new rule is to process the other family members’ applications separately automatically without a request. But they didn't indicate RQ.

What happens to my family’s applications for citizenship if there is a problem with one of our applications?
You and your family can apply for citizenship together by including your applications in one envelope. Your applications will be processed together. If one or more of the applications are missing necessary information or documents, all of the applications in the envelope will be returned.
If we receive the necessary information and documents, adults between 18 and 54 will be invited to write the citizenship test.
After the test, you or a family member may be asked to:
Re-write the written test
Attend an oral interview with a citizenship judge
If this happens, we will process the other family members’ applications separately. This process might mean that they will attend an earlier citizenship ceremony and become citizens faster than the one re-writing the test or attending the interview.
CIC will tell you before we process your family’s applications separately. We will also send you a form that you can use to ask us to process the applications together. If you want the applications processed together, we will pause the other family members’ applications until after the second test or interview.
If citizenship is then granted after the second test/interview, all family members will attend the same ceremony.
