Okay? Weird comment.

The scale may not be typical, but the pattern (many more screenshots copied to clipboard than saved as a file) is something I see across all kinds of users around me, be they technical or even very much non-technical.

Let's not turn the defaults into "The Homer", okay? Allowing the user to choose their preferred action in the same step as allowing them to change the outline doesn't make things unnecessarily confusing, doesn't add unnecessary clicks, or anything else.
