I want those things included, at least by default. A screenshot normally captures the user’s screen size, brightness, zoom level, font choices, etc.

It is often important to people that the screenshot is an accurate record of what was on the screen.

The effects of cramming 2 separate workflows and 5 features into one thing called "screenshot" because anything else would end up with something too complicated for users to understand the interaction (sarcasm that figuring out what the behavior is locked to in these scenarios is just as confusing).

While we're at it, this "share" containing the copy/paste flow is the exact same kind of thing. And screw whatever logic decides to copy the URL of an image instead of the actual image sometimes from Safari when I select to copy it!
