Is there a way to get the exposed filter values of a views block?

Problem/Motivation

I would like to use the exposed filter values of a views block in an ECA process. The values in the exposed filters will be passed on for further processing within the ECA model (in combination with VBO processing).

I can achieve some results with Event: Views post render, Actions: Get url query params and Write / read temporary store combination (or alternatively via the Get contextual filter action). But this solution only works with page reload, every time I select a new filter value, which is not very user friendly. I would like to use the exposed filter values without page reload, rendered via AJAX.

Is getting views exposed filter values currently possible? Or could this be a valid feature request?
