Admin API and arrays

[subnetmarco]

• We support sending arrays with an explicit array index param[1]=v1&param[2]=v2. We should also support adding arrays without an index in the form of param[]=v1&param[]=v2.
• Evaluate removing the comma separator in favor of arrays.

I don't see why we would drop the comma separated way of passing arrays. It would be a breaking change.

Instead we should advocate the array way of doing things, but not breaking the comma separated ones.

the underlying problem is fixed in #1399.

[subnetmarco]

The way I see it, the comma separation is just a non-elegant solution to a problem that can be already fixed with form-encoded arrays using square brackets.

[Tieske]

Hmmm... do we want to break backward compatibility because on non-elegance?

Addressed in the new Admin API - entities are now slowly migrating there.
