Apple won't remove OGL support for years, but in the meantime now you know they aren't going to put engineering time in newer OGL features or specs. Microsoft OGL on Windows Classic is a shim to whatever the graphics card maker provides. Effectively there are no OS that ship legitimate and non-deprecated OGL support today. Android AFAIK is the only platform that ships/mandates OGL ES. There are shims to support OGL ES based on the platform 3D support, such as one GitHub project Microsoft published that uses DirectX or one that I believe ships as part of Steam on Mac platforms. AFAIK there is no platform that ships and mandates Vulkan. Unfortunately Android does not require it on new devices yet. This is really more like Apple deprecating their OpenSSL libraries - they are telling people that Apple isn't going to maintain it going forward, so you should stop using their copy and bundle your own.
