An application that can "just use an atomic variable" can also "just set an
easy option" and get the exact same effect, right?

This suggestion reads to me like a work-around for you not wanting to change
code in the place that would afix the problem, but you rather propose and add
a new public libcurl function call so that you can do the change elsewhere in
your app. Generally, having two ways to do the same thing is bad.
