I also don’t like to work around this by changing the package names.  I
thought of allowing multiple versions via property, but it’s not clear
how it should behave.  I’d want to have only major versions appear as
non-conflicting and still prevent the installation of variants of the
same version.

The next question then is if the property should be a procedure that
takes the current and the potentially conflicting package as arguments
and decides whether they are conflicting, or if this should be handled
centrally when the property is present.
