This might be a superior for Delete Selection mode.
If we want to promote it that way, we should choose a better
name that CUA Selection mode, because most people won't know
what "CUA" means.
cua-selection-mode is far more intrusive though, as it adds
"shift-select" behavior (all shifted movement keys implicitly set and
activate the mark if it hasn't already been activated). To implement
that behavior both adds a post-command hook, and rebinds a bunch of very
common commands.
