Besides routing protocol convergence is there any service issues with
running mismatched MTU? Assuming the packet flow does not exceed the
smallest MTU value.

Has anyone run into a situation where the MTU at one end of a link

catch it?
In general, do you see any need for a debugging tool to be
standardized to find such mismatches?
Performing a ping with a large packet size '-s', and/or with packet
fragmentation turned off '-M do' have been our primary tools for finding
MTU (layer 2 and layer 3) mismatches.
