Empty Dependency

This is why the suggestion to standardize the ability to use the data from a dependency in a dependent plugin's activation condition was brought up, and it turns out to be convenient that we always run dependencies of a plugin even if that plugin itself has a condition that tells it not to run.

But at the moment there's no fully supported way to get at the data from a dependency from within a plugin's activation condition, it's something we're looking at.

In practice, I just let the system build invalid search queries that will have predictable empty results to deal with these cases. It's a little more overhead, but my cases are not frequent.
