I agree some people could want aspect-ratio: 1.6 / 0.9 to work. I would go
further and say negative numbers could be allowed as long as both numbers
are negative (so the outcome is always positive), i.e. -16 / -9 works too.

Now, the only case I see where this would be useful is when the property is
generated from inside a script, so the developer doesn't have to perform
range reduction on the values. Convenient, but is it really needed?
