How could it not be changed? Unless something dpkg-diverts /bin/sh
away from dash (which sort of conflicts with dash possibly
dpkg-diverting it away from bash) then dpkg will overwrite /bin/sh
when it unpacks the new dash. So unless you tell dash not to divert
and then add a dummy diversion of /bin/sh from dash before updating
you will get /bin/sh changed.

Or dash could have preinst code that adds the diversion on itself if
it detects it is being updated from a system that has bash as
/bin/sh. Didn't see a plan for that. If that is planed then be a step
forward.
