David would do no such thing because searches have to end up at the
correct corresponding buffer position, not inside of some overlay
property. Which is not even possible if I do a search and replace on
a string bracketing an overlay boundary.

I think it is a bad idea. What about matches partly in the text,
partly out of it? What should get displayed?
The underlying basic unit of a buffer is text. If you don't want it
manipulated as text, then don't use text in the first place. Of
course, this means that we might have to rethink using "x" as a
character to carry images, and use something non-printable. Or it
might be a good idea to have a property to mark text non-searchable
completely for this case. But we should not build a completely
separate reality just for searching.
