An alternative that is still not pretty, but at least keeps the ugliness
in the packages related to the switch and is fairly straightforward to
implement, would be to make the new dash pre-depend on a new version of
bash and have the maintainer scripts of bash preseed the dash template to
false if:
- bash is being upgraded
- the dash template does not yet exist
