Linking - yes things should fail fail at linking. The spec clearly says that
one should use eglGetProcAddress to get the function pointers.

Runtime - nope. The extension defines the means, a device is not guaranteed.

Also ... I really hope that Nvidia fixes that blog - it contains a number of
fairly fundamental issues.
I reached out to the author ~1year ago listing all the bad stuff but never
heard back :-\ Oh well
