The problem with intelligence collection is that you cannot afford to have just one knothole through which to view the world. You need several different perspectives to be sure you are not seeing figments of imagination, or being fed malarkey. But how do you reconcile the perspectives? That problem still exists despite what happens to the CIA. The CIA is a case where a wartime agency, the OSS, gained influence and dominance over all intelligence product, thus providing a unified---but curated---picture. Other agencies (e.g., DIA) used to provide competing collection, but have been subdued over time.
In any case, the present CIA has a huge backlog of portfolios, data, and infrastructure and any rational disposition will need to have a severe inventory process.
