* GL_EXT_buffer_storage is a GL ES 3.1 extension, and it defines the glBufferStorageEXT function, not glBufferStorage (and unlike GL_ARB_buffer_storage, it doesn't define glNamedBufferStorageEXT).

* According to https://registry.khronos.org/OpenGL/extensions/EXT/EXT_blend_equation_separa... "Issues", ATI_blend_equation_separate is also a different extensions that doesn't have a specification but defines slightly different tokens. I don't think it should be aliased either.

* Then GL_EXT_multi_draw_arrays is probably okay, as both names are indeed listed in https://registry.khronos.org/OpenGL/extensions/EXT/EXT_multi_draw_arrays.txt
