It could be helpful to have an indicator on a profile's DNA Connections if there's an Uncertain parent along the connection between the profile and the tester. For example, take the case where the paper trail says that three men descend from the same paternal-line ancestor, Y-DNA testing says that one of the men has a different paternal-line ancestor from the other two, and it's not yet known exactly where the NPE happened. The person with the different Y-DNA would be understandably hesitant about breaking the paternal line when they don't know where the line should be broken, but until the line is disconnected, the tester will show as a possible Y-DNA match on profiles that they actually don't share Y-DNA with. If the unverified fathers were marked Uncertain and that information appeared on the DNA Connections, that'd make it clear that there's a possible issue with that line and that further testing is needed.
