Yes there is a reason: many of us don't want user accounts
automatically added to our local passwd(5) & group(5) databases,
as we prefer to manage this ourselves.

postinstall(8) is intended to detect issues to be rectified
after an upgrade, and if possible, fix them in a safe manner.

I've experienced situations where automatic updates of end-user
modifiable system configuration has gone wrong.  As such, a
design and implementation goal of postinstall(8) has been to
make it "safe" whilst staying usable.
