Array helper - more function required

I have gone through the ArrayHelper file and found only one function.

There are multiple functions which we use in our development, which we wish to have in core helpers

Can we suggest those as well to be a part of core functionality instead of custom?

This might help all developers to get the one-stop solution

Suggested functions can be,

1. array_sort_by_column
   
2. array_remove_empty_elements
   
3. array_search_by_key
   
4. array_search_by_value
   
5. array_change_key_case_recursive
   
6. array_trim
