Data loader query param tracking questions

[nerdoza]

The documentation seems a little vague on what exactly is tracked in a data loader query. In-route parameters effectively cause data fetching, but changes to query parameters are hit and miss. Sometimes they appear to cause fetching of data, but other times they don't.

So first and foremost, are query parameters tracked?

If so, what makes them so flaky?

And if not, what needs to occur for them to be tracked? Is there a reason they aren't currently?
