If you're running a hosting server, and have many customers using the
same app, it may not be practical to bump them all at the same time.

* They may have different busy periods during the day, making it
impossible to schedule a common downtime.  
* Many upgrades require manual steps - it's less disruptive to upgrade
each installation one at a time.
* Different customers may want or need to run different versions of the
same app.  If a customer is happy with what they have, they may not wish
to upgrade.

If you don't have USE=vhosts set, then the eclass will automatically
unmerge the older version.  If you have USE=vhosts set, then you're
telling Portage that you need the flexibility of running webapp-config
manually.
