Something is missing from your sentence. 

What is the alternative that you view as worse?

Juast as a point of information.  In general when bridging is desired but not possible people deploy proxy arp.

I completely fail to see how having the VM output to a tun interface and then routing that, would not be supported by current solutions.  I believe that is where VM solutions all started networking wise.  Outputting to an interface is needed to support interfaces like 802.11 where bridging frequently does not work.
