So, let's say you set up an EL7 system with stock everything, and then enable epel with dnf install epel-release or equivalent. You now get the stock epel mirror listing, not a custom package Amazon rewrote, and they'd need to add a custom mirror that provides an override for that package to make it work that way. So I would _guess_ one or more large companies migrated a bunch of things onto cloud hosted EL7-based system after EOL meant god help you finding new hardware support. (I would also guess either EPEL doesn't have a mirror on Amazon or it should have auto-picked it, or the auto-picker is bad, and either way, Amazon will probably go "oh our bad", since I believe they host local mirrors of things anyway...)
