As seen during a ‘guix package’ demo at FOSDEM, downgrades are reported
as upgrades as of 0.8.1.

I don't know about this one, but another problem with our upgrade
command is that it mishandles outputs other than "out", at least in the
console output.  It _always_ says it's upgrading them.

Fixed in 46b23e1:

--8<---------------cut here---------------start------------->8---
$ ./pre-inst-env guix package -p foo -i guile-1.8.8 -n
gnu/packages/guile.scm:50:2: rimarko: ni uzas guile-1.8.8 sed guile-2.0.11 disponeblas unuanivele
The following package would be downgraded:
   guile	2.0.11 → 1.8.8	/gnu/store/660m94139bka6mi7bdja5nvvqwq61zkk-guile-1.8.8

From a quick check, ‘manifest-transaction-effects’ reports the right
thing when upgrading just a single output.

Could you send an example that illustrates the problem?

TIA,

Now, pseudo-upgrades are reported as downgrades. Namely, when the version
number of a package does not increase, but something changes with respect
to its inputs. I would suggest to treat them as upgrades.
