Good idea. I think we should setup a new bot for Qt5 trunk to catch source incopmpatible
changes early. It is possible to make a bot build the latest Qt5 hash if there is a new one.

OK, so I stopped weekly update and I will do update only on demand.

> - If anyone reaches a point where a Qt5 upgrade is needed, open a bug and follow the same procedure we do now, no need for a huge concensus or to wait for the next weekly update.
Correct. But it would be great if we can minimize the number of updates.
If there are two update in few days, it can be annoying for developers.

I finished this weekly update. (Qt5 WK1/WK2 buildbots, perf bots, EWS) The latest
Qt5 hash is 65079e2706bf820cb2e585039f005a8abda151f8 now. Simon's WebKit buildfix
for the newer Qt5 landed in https://trac.webkit.org/changeset/123476
