Why not keeping the shard xlator always on but set on a very high value so that
shard is never happening? Something at 100GB (just as proof of concept)

Ok but:
1) that's for 3.7 *beta1*. I'm using 3.8
2) "advisable" doesn't mean "you have to". It's an advice, not the
only way to disable a feature
3) i'm talking about a confirm to add in the cli, nothing strange. all
software ask for a confirm when bad things could happens.
