   @randolf-scholz thanks for raising the issue! That would indeed be useful addition. I am going to close this as a duplicate of https://github.com/apache/arrow/issues/20486, since that already exists for adding such an option to the cast kernel.

   I understand that this would give a workaround, but I would say that ideally we have that option, and then this one might be a bit specific? 
   As you show, we already have the `utf8_is_numeric` kernel, but the problem is that this is too simplistic and fails if there is a "+" or "-" in the string, or a thousands separate, ..?
