I know (I assume) that repquota output for my root and www users will be broken, and that's fine - I just want to make sure that as soon as one user goes over 2TB of owned files the filesystem doesn't trash itself.

I think there are not so many users running similar configuration, it 
means not much experiences. But you can try your own test easily. Just 
install some test machine and try it with large sparse files
(something like dd if=/dev/zero of=sparse-file bs=1 count=1 seek=1024k 
for 1M sparse file)
