Please provide a patch that makes the behavior you want optional.

I could try to come up with a patch myself but since you already have
coded such a thing why duplicate the efforts?  IIUC we also have to
decide whether and how to expand your code to desktop saving and how
to handle buffers that got killed in between saving and restoring.

Later we can decide whether to install it as default.
