If we can always trust the browser (and its vendor) to be on the user's

Perhaps it should have been possible to decide via CSS and media 

The most common problem today is, I think, to _prevent_ the user agent 
from autobuffer. I assume that the reason e.g Webkit has been eager to 
buffer things, has been in order to provide a better user experience - 
my theory has always been that improved user experience has been the 
motivation for this. Therefore I can very well understand that one is 
sceptical about putting the ultimate judgement into the hands of the 
user agents.

Can we be certain that the user agent _does not_ autobuffer when the 
autobuffer attribute isn't used? Or is this also up to the user agent?
