I think read-only overlays could be very useful. For example:
1. Create a command called `mask-regexp'. It creates read-only overlays for
matching text throughout the buffer.
2. There should also be a way to add manual masks, using `mask-region'.
3. Now use `replace-string' or any other command to bulk transform text.
However, masked text is not changed.
4. Then execute unmask-all, and the mask disappears.
This method of editing is key to video editing workflows. I think the only
reason I never thought to use it in Emacs is because it's never been there
(and so never occurred to me until now).
