I would point out that none of the conversations I can recall having ever resulted in more than fire-fighting - perhaps one or two adverts may have been ejected from the pool but the overall problems persist. Perhaps I'm misunderstanding your point, but the assertion that steps have been taken to address the overall picture for RSW specifically are, as far as I'm aware, untrue.

In the interests of working with recent information, I tested a few pages in incognito mode before I managed to find one with what I believe to be 2 broken scripts running in a seemingly infinite loop and another that cleared my JS console for no obvious reason whatsoever (perhaps it was trying to hide it's errors?). This was in addition to a number of other broken scripts. Unsurprisingly, my laptop started feeling the strain from these few pages being open in parallel, yet it can have dozens of tabs open with adblock running.

Apparently, the performance improvements advertised have yet to come to fruition.
