Suppose the gem Foo depends on the gem Bar. Foo exists in Source
A. Bar has some versions that exist in both sources A and B. At this point, the API request will have found all the versions of Bar in source A, but will not have found any versions of Bar from source B, which is a problem if the requested version of Foo specifically depends on a version of Bar that is only found in source B. This ensures that for each spec we found, we add all possible versions from all sources to the index.
