Yes, it was an idea of the student Paul Magrath and he implemented this
as part of the GSoC project.

To achieve the same we could run the destroot phase as user macports and
only use root if destroot.asroot has been set. Privileges of the root
user should only be required for setting file ownership.

Running destroot with a regular user account reduces the risk of
overwriting any files on the system, but it still might wreck data in
your home directory or anywhere else owned by this particular user account.
