Any possibility that the iOS8 driver could be updated to include a way to support timer queries?

ES 3.0 doesn't contain timer queries, and the EXT_disjoint_timer_query extension is not listed for the iPad mini retina (PowerVR SGX543MP2) or iPod touch 5th gen (PowerVR SGX543MP2).

EXT_disjoint_timer_query is listed natively for the Nexus 4/Nexus 7/Asus PadFone X (Qualcomm Adreno 320), Nexus 5/Samsung SM-G870 (Qualcomm Adreno 330). The Xiamoi Minipad (NVIDIA Tegra) supports ES 3.1 which has timer queries.

Since the SGX543MP2 is a pretty powerful chip, it seems plausible to me the capability could be there in hardware.
