this doesn't sound like a "minor task" to me. The only way to have per-project non-sharable settings has been removed. Now only global per project settings are available in settings.xml.
It will cause me headaches in netbeans IDE integration eg. the deployment server TYPE is noted in the pom.xml as it's something that is usually shared across all developers, but the deployment server ID is stored in profiles.xml file because the ID token value is user installation based (can include path to the server installation)
