For what it is worth we need to switch to the 10.7 SDK for ESR 38
anyway. See: https://bugs.torproject.org/12761. Thus, we might want to
start early (i.e. after ESR 31 based bundles got out) which would allow
us to solve one blocker for the ESR 38 based release beforehand. Note,
though, that switching to the 10.7 SDK is perfectly possible with
supporting 10.6.
