I'm not sure we have full data on the question, but by my own experiences the default expectation for most people regarding version control is copy the file and rename it. The default expectation for most people on collaboration tooling is sending an email. If they consider such things at all.

We can easily define a niche within which GitHub-awareness can be presumed but it's certainly not "most people".

I suspect the majority of people who come to GitHub with intentions other than contributing come either to skim the README for installation instructions, or to complain about a problem. They may not even know about git. This is the wide kind of GitHub-awareness, which still assumes a level of computer literacy above that of most people.
