Not arguing against, but would you happen to have example where
MST does not fit? All my respect to the person who decidedly
engineers L2 network with more then 65 planned and documented
topologies[0], and succeeds to deliver higher SLA than what is possible
with fewer.

[0] 2960 can handle 65 MST instances, http://www.cisco.com/en/US/docs/switches/lan/catalyst2960/software/release/12.2_46_se/configuration/guide/swmstp.html#wp1034497
