Ok, this means I could replace the default “hostproblems” view with a custom view which contains an additional filter. If this is possible, it’s worth a try.
Hmm, this could cause confusion in the team “Ok, there are still problems left … loading list … no problems found”. “Hey mgutt, solve this bug in the sidebar” 
Do you now confirm my opinion regarding “the soft state already triggers an unhandled problem, which I think is incorrect”? Then I would open a feature request regarding this.
