 From a general perspective:

When I hear "replica" it evokes a "clone", something equal/identical.

Based on this, the expected behavior for me would be that:

- if master has DNS and CA, then the new replica would also have DNS and 
CA (without any configuration option needed).
- if an optional service is missing then replica wouldn't have it as 
well by default

This would required reverse options like: --no-dns.
