   A related topic is having kernel specializations based on function options or other non-type factors (template specialization is used for type-specific cases). [For the `binary_repeat` function, there are two specializations based on the number of repeats requested. The dispatching is done at runtime](https://github.com/apache/arrow/blob/master/cpp/src/arrow/compute/kernels/scalar_string_ascii.cc#L3462-L3467). Could an approach similar to this be applied here?
