While I (a client) and the reddit thread creator (who neither I nor the bug reporter know) do use Optifine on our client instances, it's unable to be installed on a server and should therefore be incapable of affecting server-side mechanics such as mob spawns. Attached is a screenshot taken from a vanilla instance, on the bug reporter's server (which is what lead us to discover this). There still appears to be no mob counter where it would be expected.
