Should Hubble change its proprietary period policy?

Is there a better way to operate Hubble in the coming years to maintain or increase its science return per dollar?
What Hubble instrument(s) or capabilities constitute a minimum operational set? How do we, the scientific community, help the public "let go" of Hubble some day?

Testing Assessment Task
Budgetary, technical and schedule concerns related to cryo-optical test plans reviewed at the mission CDR led to the formation of an independent, external task to review integration and testing plans for JWST Reviews sought on ISIM and OTE integration and test plans and science requirements driving those plans

ICRP To Examine
1. The technical, management and budgetary root causes of cost growth and schedule delay 2. Current plans to complete development, with particular attention to the integration and test program and management structure 3. Changes that could reduce cost and schedule or diminish the risk of future cost increases without compromising Observatory performance 4. The minimum cost to launch JWST, along with the associated launch date and budget profile, including adequate reserves
