Environment

• Kendo UI version: 2019.3.1023
• jQuery version: x.y
• Browser: [all]

In order to fix concerns from #241 (https://github.com/telerik/kendo-ui-core/issues/241) the Autocomplete now shows a full list of items when the text entered has been deleted.  This ignores the MinLength option, and can cause unresponsiveness in the browser (since MinLength is generally there to reduce the amount of results).  From #574 this new functionality is intentional (and as such, the thread was closed as won't fix), but in practical terms, this causes issues for a lot of people.  If you really don't want to enforce MinLength when 0 results are returned, perhaps adding an extraoption like 'AlwaysEnforceMinLength' would solve this problem

I was looking into why the data value of the Autocomplete control was not submitting to my controller via an ajax form and came across this article: https://www.telerik.com/forums/autocomplete-send-selected-dataitem-to-controller#-BRzEKVnbUyebqxFKYWpcA. Would it be possible in a future release to include a dataValueField option so that the value of the data item selected can be used by the controller? What's weird is this is not an issue when using the autocomplete control inside a grid. I was able to get the value and update my model.
