requests to endpoints are via GET and for choices there is by default query string of all values from the form
url length is limited tho
so there is now a way to turn it off with data-select2-full-state
but if in the future someone needs dependent selects, the JS IommiSelect2.initOne may be tweaked to use a data attribute with json list of fields that need to be send to the endpoint
this is a "when needed" kind of ticket
