Usually they claim "it's Cisco proprietary, MST is a proper standard!!!!"
instead.

We have lots of customer setups with ~ 3-4 VLANs each, two of these connecting
to our gear (management network and external/production network) and the 
rest spread across a wild mix of different switch vendors, some of them 
not even getting MST right.  Fun to debug.  NOT.

MST seems too complex for an average coder to get right...  (it's definitely
too complex for your average network admin).
