You're trying really hard to fit this into your binary model. Security is all about managing risk. It's not absolute. TLS didn't change when the CRIME attack was revealed, but it suddenly became less secure because the risk profile changed. But before CRIME, TLS wasn't perfectly secure. There was always the risk that the protocol could have undiscovered flaws, that an attacker could guess the private keys, that a cert authority could issue a valid cert to an attacker, etc.

In a world of imperfect security, talk of binary security is meaningless.

Security is all about managing risk for you because you've already chosen to compromise on security.

Not compromising on security is an unrealistic ideal. A perfectly secure system is a perfectly unusable system.
