Usage is of course irrelevant, what counts is how many free ones are 
left. This number is well below 70%.

We would be better off upgrading to 32 bits AS numbers sooner rather 
than later (unless we're confident we'll never run out of 16 bit ones) 
because this way there are enough 16 bit AS numbers left. The current 
32 bit AS number proposal (that has been around for at least 4 years 
now) should work very well for routers that aren't upgraded as long as 
only leaf sites use the 32 bit AS numbers. 32 bit AS numbers for 
transit ASes are best avoided until everyone has upgraded.
