Right, if there is no significant change this will work, if there are database changes, you should run engine-setup again to perform upgrade.

However, you do able to remove the entire environment without cleaning database, just run engine-setup and then reset password using:

"${HOME}"/ovirt-engine/bin/engine-config -s AdminPassword=interactive

And you will be able to login, but lose encrypted storage secrets.

As files are only added, there might be side effects.
If, for example, dbscripts were modified, you may have duplicates etc..
In this case you can remove $HOME/ovirt-engine/share/ovirt-engine/dbscripts before install-dev.
There can be other side effects if packaging files are added.
