So this could be the case for all group and all long simulations, and if
we push the idea this could apply to all simulations :
- esmControl
- esmFixClim2
- past1000
....

So one should have a clear decision on that leading to a simple rule.
All simulations can be published before the full official length run is
complete or not (piControl minimum official length is 500).

I would vote for *not* in this case. So you can publish once you reach
the minimum duration, and then you can republish later with longer
simulation if you want to, but in a sense it will be a new version (just
longer version).
