Totally agree. And quick iteration is the nut of Linux especially for personal usage. But in enterprise scenario, there’s normalization. That is why LTS and subscription make sense. I am not gonna troll in 《cathedral and bazaar》. ^:^

Originally I am thinking about downloading rpm packages from EPEL and merging these packages into 7.3’s ISO file. But it seems rebuilding from source is also a good approach!  I will try this way later.

Little bit off-topic, the main purpose to play OL7.5 is to taste kslice and dtrace though UEK can be installed/built on SL too. If there is feasible hot-kernel-patching, quick iteration will dominate more in enterprise on-premise demand.

EPEL always tracks the latest RHEL minor release. If you decide to ignore  all the security risks associated with the lack of updates and prefer to freeze your system at an old(er) minor release of RHEL (or clone) you will need to grab the sources of the updated EPEL packages and rebuild them youself for your environment. The EPEL project lacks the resources needed for such a task.

And BTW , you can install the latest EPEL packages on OEL 7.5 because it has the updated packages that came with RHEL 7.5 (and which, incidentally, will land in the CentOS world very very soon as well). 

If you really must use an old minor release you probably should subscribe to RHEL EUS. This will ensure a better approach to the security aspect but will not solve your issues regarding the  compatibility with EPEL. And pretty please, do not imagine that a system not facing the Internet is safe. Stuxnet infected air gapped computers.
