Mesa doesn't implement EGL_EXT_device_enumeration yet, so this isn't entirely surprising.
Then, shouldn't I be getting either linking or calling errors?
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
