Looking at the example patch you used before, (which hasn't merged yet)
I see this as a combination of factors:

On one side, the fact that we are launching jobs that would not be
affected by the patch. This increase the number of jobs on a single run.
In these cases even without a permanent solution I tend to create a
temporary patch for CI that removes every job and runs the only one I
need, and make my patch depend on it.

On the other side, there's our excessive reliance on end-to-end
integration tests (when we deploy everything to test our code, we also
have to collect everything). Because of the poor execution paths
coverage we are getting from these kind of tests we tend to err on the
side of caution and add several integration tests to be sure we're not
breaking any other execution path. This also increases the number of
rechecks needed, as we take more time and resources to discover that a
PS has broken an execution path.
Shifting our strategy to use more functional test would help in this

It would be interesting to gather statistics on what repos trigger the
most jobs, and see where we could start reducing.
