Hey i haven't touched these packs in years, but you bring up some very good points.
though I'm not entirely sure how other people would want licenses presented, and its proving surprisingly hard to track down examples within other works. if you would like to link or present any examples with your licenses then that would be a great help
It can be really hard to find a good example, yeah. https://somepx.itch.io/ does a good license presentation in their packs - it's basically just outlining the cans and cants and the intention of the license (which is basically just 'don't share, do use in projects, do attribute credit').
The most important thing for me is just taking the blurb you've put on itch.io and saving it inside the artpack so it can 'survive' okay when isolated.
