force doesn't force all the way?

[Roger Pack]

Hello again.

When I changed my variants.conf file to be "+universal" for all ports,
then ran this:

$ sudo port upgrade --force installed

I am presented with the addendum, which leaves me wondering...is this
expected? Didn't I "already" force?
Thanks!
