The problem still presents when you have a BelongsTo with searchable()
When you want to create a new record the search is still case insensitive.

Example (Product have a json name field)

BelongsTo::make(__('Product'), 'product', Product::class)
                ->searchable()
                ->sortable(),

I believe you can come out with a custom relation search class if you need it right now. Since this change the current behavior I'm putting it under feature request for now.
