I would say the risk is due to implementation.  If the vendor's gear
vomits quicker due to a resource consumption issue in handling MD5, is
this really a problem with MD5?

These issues can usually be fixed by simply improving the scaling
properties of the implementation that may be required during adverse
conditions.
