If a project B use project A as a junction, B should not try to use the bst remote cache of A (at least by default)

Opening a new issue, this has regressed #401

Same reason as before. If project A is popular, this will literally kill the cache server.

Though seems current behaviour is potentially worse than how it was back with original issue. Current behaviour is project B cache is never considered for project A artifacts meaning when the artifacts go out of cache for project A, they will never be considered cached.
