To add some context the feature that I am asking for is working DRI3 +
present ... with mesa 10.2
it gives us GLX_EXT_buffer_age which finally fixes tearing issues in
mutter that some user are experiencing
without using workarounds like forcing the compositor to always redraw
the whole screen (which costs performance
and battery life).

The whole effort to fix it started in January 2012 (!) so its not like
it is really urgent now but given that things got fixed now
(xserver 1.16, newest intel ddx snapshot, mesa 10.2) .. I rather have
it on user systems at some point (and get rid of inquires on "when is
it going to get fixed?").

NVIDIA just released a driver that runs with the xserver 1.16 abi ...
not sure about their legacy branches and fglrx though.
