BOAC,
the Toronto session at the 2010 AIAA Guidance, Navigation and Control annual meeting was just one waypoint in a long history of targeted research on LOC.
Any "initiative" started long before, with targeted research programs. For example, here an article on
Loss of Control from the AAIA organ in March 2003. NASA Langley's work was well represented at the 2010 AAIA GNC meeting, it seems, as one would expect from such a research program.
I can't find the papers yet on the Langley server, but there appear to have been two contributions from NASA Langley on safety research to the AAIA GNC annual meeting last year (Chicago, 2009). Here is one:
Aircraft Accident Prevention: Loss of Control Analysis, and here is the other:
Methodologies for Adaptive Flight Envelope Estimation and Protection. Neither appears to be directly related to your concerns about unremarked longitudinal trim changes.
