Description
There is often a * added by CSS used in order to tell if a field is required or not.

When I use a CollectionType, I do not want this * since adding a row to the collection is not required

The * could be considered more like telling that at least one row should be added.

But if I use required => false on the CollectionType, I lose the required attribute on all the children

And I'm looking for

As explained in Follow up of #39943
It's a general rule for Form and child, but it seems weird for Collection.

Maybe the rule issue is with the required attribute of a CollectionType.
To me, it does not have a lot of sens, what is a required CollectionType vs a non required CollectionType ?
Both will submit a collection.
