Collapsible code blocks is an excellent suggestion! Unfortunately, it would seem medium.com doesn't yet allow for markup code in their articles. However, I will try them out in my own library packages README files. Nice find, Jp.
Indeed, if the gists were collapsible or ‘adjustable in size’ in some fashion, they would be reconsidered. I promise to keep an eye out for alternatives.
As for ‘making it hard,’ I don’t feel one click or tap on a screenshot is particularly difficult. Regardless, your remarks on the subject have certainly been noted.
