Sure. I was just twitting the OP for having not considered these
issues.
Given that you can get at that behavior by dividing extract(epoch)
results, I tend to think we should leave well enough alone. If someone
did come up with a brilliant definition of what interval division should
do, it would be pretty annoying to have already locked ourselves into a
not-so-brilliant definition ...
