Because go/packages presents each synthesized test main package
as a first-class package, the tests now analyze all of the dependencies
of "testing", which they previously avoided. This makes the tests
slower and the resulting call graph much larger,
so they now look for a subset match, not an exact match,
on the set of graph edges.

(This functionality is provided by the oracle, but its output
format is inflexible, and the functionality is better suited
to a shell utility. I may remove the oracle 'callgraph' feature.)
