You probably use it the way many users do, and I wouldn't be surprised if that happens someday.
But it's mostly just a sign of how almost nobody actually cares about the code now, and just use GitHub as a source of free libraries that may as well not have source available at all.
For others of us, a README is something we may briefly read once or twice when first considering or integrating a project, but the repo's code is where we spend way more time -- evaluating quality, tracing potential bugs, unearhing quirks and overcoming sparse documentation, considering whether a fork is needed, etc
But that's all hokey old greybeard stuff these days.
