When we throttle load of <head> referenced script, yes, trackers can be even there (see cnn.com), we prolong time to window.onload.  That's undesirable.

self explanatory.  reason: some trackers can be referenced in <head>.  when we slow them down we postpone onload event.  That handler may easily trigger load of a vital display content dynamically, hence, it makes sense to never throttle leaders.
