Your suggestion only seems to work if the software in the package is stateless. In the case of a DBMS the approach would just put data upgrade problems in another place and in some cases make them harder to solve as well.

State is a different problem. Usually programs don't mutate their executables.

Mutable, persistent state is usually put under /var and is user-owned. Package updates should not touch data in there.
