Masaori, Sounds like good reasoning. I am completely ok with moving the minimum with 1.0.2 as long as CentOS 6 is dropped at the same time.
WRT the vulnerabilities in 1.0.1, RedHat has been cherry-picking back security fixes from newer openssl's into their Openssl 1.0.1 version, so it is probably not that dangerous to use it.
