That's why I vastly prefer stats from the actual CDNs and content providers
that aren't generated by speed tests.  They're generated by measuring the
actual performance of the service they deliver.  Now, that won't prevent
burden shifting, but it does get rid of a lot of the problems you bring
up.  Youtube for example wouldn't rate a video stream as good if the packet
loss were high because it's actually looking at the bit rate of
successfully delivered encapsulated video frames I _think_ the same is true
of Netflix though they also offer a real time test as well which frankly
isn't as helpful for monitoring but getting a quick test to the Netflix
node you'd normally use can be nice in some cases.
