For example, the last EUS release for EL5 was 5.9, and it was EOL'ed by Red Hat on 2015-03-31 [3], even though the main release (5.11) is still supported until 2017-03-31 [3].

RHEL/CentOS 5 have an old openssl package 0.9.8e, which doesn’t have support for these ciphers and TLS 1.1+ as well as no SNI support, so doesn’t provide the level of capabilities most PHP 5.6 installations would benefit from.

Whilst using this, RHEL servers would continue to get support for base packages, the IUS EL5 repository would effectively EOL php56u on that platform version before php56u becomes EOL, leaving EUS supported servers unable to update even when php.net is still releasing updates. I doubt EUS subscriptions are used much by servers using IUS though.

This could present a problem for some IUS users, since we don't currently package php55u and php56u for EL5.  Users still on EL5 will not have any options for IUS php packages.  We've already decided that we will not offer any new packages for EL5 [2], but we are considering making a one-time exception for this situation.
