You should provide the feedback on the Github repository, it will be easier to address a solution for that :-)
1. how do you indicate the crop/anti-tamper in your URL? What is the URL structure of your responsive images?
2. you can finely control how Imager is targeting your images. So you could target different imager configurations for different classnames.
Have a look at the examples and let us know if something is missing and not addressing your needs :-)
The segment immediately after the hostname is the signed part, which is generated based on all the other parameters (ie quality, dimensions, crop coordinates and source image url). If you change any part of the URL, the server will return a 404. There's no way of providing a set of client-side rules for how to generate the URLs for the different size images, without leaking our secret key. An option would be for the entire URL to be the configuration, but then all you've achieved is moving the config out of data attributes and into javascript config objects.
