I'm also concerned that clean-buffer is too vague a function name, and so the scope of its behavior is not clear. I can see that some programs may want to "clean a buffer" by eliminating text properties and overlays but not killing local variables, whereas others may want to do all three and potentially something else.

At this point, I'm open to letting this patch go ignored.

Thank you for considering this idea with me!
