Several people can upload merges.
One person looks after integration in qt5 and all its sub-modules.
We can spread the load (indeed, I carried it for a few weeks while
Liang was on holiday), and I believe module owners can do their own
merges (which saves the integration team work), but the integration team
takes responsibility for ensuring merges are happening.
So it ends up being that Liang, as integrator, does most merges.

I shall amend sanity-bot to object to cherry-picks to LTS unless they
come from gerrit/stable.
So "it has passed CI in dev" won't get it into LTS.
It has to have passed review and CI in stable to be a candidate for
cherry-picking to LTS.
Then the second review can haggle about whether it belongs in LTS.
That can take a long time without delaying the change's merge-journey up
