I would like to work on this task.

Thanks for your interest in json-tricks and for your offer to help!

I'm not generally in a hurry to unsupport older versions unless I have to. Do we get any amazing features in 3.7+ that make it worthwhile?

Plenty of things including dataclasses, improved type annotations, and better handling of unicode data.

Dropped from our test matrix in https://github.com/mverleg/pyjson_tricks/pull/110 as it was removed from https://raw.githubusercontent.com/actions/python-versions/main/versions-manifest.json
