Speaking only for myself: No. The L2 IXes I connect to should use their
resources for packet switching, not filtering. Way too many things that
could go wrong if we go down the filtering path…

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.
