Indeed. Most of the L2 IXes run on very “cost-optimized” solutions
just to switch as fast as they can without going in details of what
actually is being switched - at least in Europe. 

To do some additional checks would require extensive testing, platforms
capable of doing this in predictable manner (stability, performance)
and obviously - a lot more work than it costs today.
