Based on what Peter said, it sounds like there has been at least one  
problem report. There was at least one more vague report made  
informally in John Resig's blog comments. Maybe we need to start by  
agreeing what counts as "absence of problem reports".

However, by way of comparison, we added a 10ms clamp three and a half  
years after the first Safari beta was released to the public, as it  
took about that long to get enough bug reports to convince us that we  
had to do it for compatibility.

Given that, I think we may want to find some more active way to look  
for potential problems and potential benefits.
