Proposal

Is it possible to have the caret from the form-select as a separate class, something like form-caret?

Motivation and context

I would be helpfull to use in normal inputs for typeahead, datalists that already use form-control
we could could also make other similar classes like times, check, loading and switch between them depending on the input state
that way we could maybe drop the form-select class, and go with form-control + icon if you want on
