Sorry if I caused confusion, but I'm not affiliated with Intel (or any other
Khronos member). So I seem not able to access the spec history.

I tried simply removing the non-OpenGL check, but it breaks another piglit
test, namely spec/egl_khr_create_context/invalid flag gles, giving
EGL_BAD_MATCH instead of EGL_BAD_ATTRIBUTE in some cases (I guess when the flag
given is valid for OpenGL but not ES). And I saw that test was updated against
version 15 of EGL_KHR_create_context_spec (commit 5f668b1 [1]). The comment
there is explains

 /* According to the EGL_KHR_create_context spec, version 15, there
  * exists exactly one valid flag for OpenGL ES contexts: the debug
  * flag.
  *     If the EGL_CONTEXT_OPENGL_DEBUG_BIT_KHR flag bit is set in
  *     EGL_CONTEXT_FLAGS_KHR, then a <debug context> will be created.
  *     [...] This bit is supported for OpenGL and OpenGL ES contexts.

So it seems allowing EGL_CONTEXT_OPENGL_DEBUG_BIT_KHR in OpenGL ES is more
reasonable. If so, I'll work out a patch and send it to the ML.
