Oh that's not the reason, the reason is that the only those formats are not valid for render buffers but for attachments to frame buffers SRGB_ALPHA_EXT is indeed valid. This is because SRGB_ALPHA_EXT can be the format for a texture attachments (as opposed to a render buffer attachment).

So to summarize:
RenderBuffers valid formats: SRGB8_ALPHA8_EXT
Textures valid formats: SRGB_EXT, SRGB_ALPHA_EXT

Valid formats for attachments to FrameBuffers: SRGB8_ALPHA8_EXT, SRGB_ALPHA_EXT
