Does enables conformance mean: Flags non conformance?
No. Enabling conformance means enabling support for the conforming features.
Flagging non-conformance is not possible in general as there are more creative fools out there than there are compiler writers.
There are zillions of ways to write non-conforming code, for example an endless loop is not conforming in C++. The compiler is not obliged to diagnose it, but it is allowed for the compiler to silently optimize the non-conforming code away, assuming it is never called. At least that's what g++ folks think.
