Hey I even wrote it in the commit message at the time,

"This adds i965 support for GL_EXT_framebuffer_sRGB, it introduces a new
    constant to say that the driver can support sRGB enabled FBOs since enabling
    the extension doesn't mean the driver can actually support sRGB."

You can expose the interface on a non-capable driver and just refuse
to accept sRGB buffers.

So the flag is technically right. Whether it is useful is another question.

Dave.
