That's not what a Conflicts field is for. It's to allow a project to say they don't support installing in parallel with another package. It doesn't matter why it's unsupported, it's making a conflict perceived by the project explicit in their metadata.

Such a field is designed to convey information to users about supported configurations, regardless of whether or not they happen to work for a given use case. If a user believes a declared conflict is in error, and having the two installed in parallel is important to them, they can: 1. Use virtual environments to keep the two projects isolated from each other 2. Use an installer that ignores Conflicts information (which will be all of them, since that's the status quo) 3. Make their case to the upstream project that the conflict has been resolved, and installing the two in parallel no longer causes issues 4. Use the eventual --force flag that any installer that supported conflicts is likely to include ;)
