The resourcing reports that are now available (Utilization and the info out of the planner tool) should be embedded into Portfolios and Programs as a standard set of reporting tools that pre-filter to the object you're viewing through.
This should be reporting that's accessible to anyone given VIEW access to the Portfolio or Program.
The ability to manage/change BUDGETED HOURS should still be handled through plan license users but there should be a consumable format that pre-filters in these embedded reports making the data much more accessible to users.
The tab(s) for these reports should be something you can then show/hide via layout templates if necessary.
