At least as of mid-2.2 series this was certainly my experience. It was

I am inclined to believe that that is the case. Unfortunately, I have no
advice to give - but I am writing because I think that it would be neat if
you have the time and the inclination for you to document your findings as
you progress and put them on the web.
