This is very nice.  I have a version of this in my local Emacs config, but it's on by default and it doesn't put the buffer in read-only more: it uses an overlay to display the rx regexp instead of the string-based one instead.  I've attached the code if you want to have a look; what's missing is logic to automatically "unprettify" the regexp when the point is in it, to make edits easy.

I was originally planning to include this in the easy-escape package, but I haven't found the time to do it, so feel free to go ahead :)
