Nathan,
The main problem as I said was the fact that the car due to it's low warp stiffness did not sufficiently quickly build up (diagonal) load transfer which lead to a rather slow build up of tire slip angles, which was generally interpreted by the drivers as a "lazy understeering pig" setup. Imagine a road car with soft roll bars and then putting some really stiff bars in it ... the car changes from day to night . ... Beyond that there were issues with roll center heights (that do also affect the LLTD) which made finding a good setup a pain. If one considers that for instance on flat surface circuits like Magny Course we put into the car the stiffest springs and rollbars in the car that we could find (to keep the tires as hot as possible ....) one can see that there are many other factors that can come into play than "just" having a good idea .....In those days I had the pleasure of working together with some of the brightest vehicle dynamics engineers and we did look at all the options known to man-kind in those days. And with us there were many other teams looking into the matter. The 90s were famous for all the developments on suspension technology. Apart from the fact that some people here in this Forum do tend to "overestimate" their seniority, I have always worked on the principle that "if an idea of mine has not won the hearts of the clients and especially if the clients are very capable of judging whether the idea works or not, something might not be as good about the idea as I initially thought". And especially having tried it myself, together with many other clever people, especially having seen what "alternative" technology can do, and especially since neither of us all ha been able to make a faster car than a "conventional" car made this particular idea no "winner". These are just some simple facts, experienced in a world where one was prepared to spend 1.000.000 £ for each 0.1sec of lap time, without any politics or "presumed" so called expert knowledge.
If anybody believes he can do better (since in his visionary wisdom obviously all the "other ones" in the past have been complete & utter idiots, or if active now, are at the least ignorant peers) this person is either the long awaited genius or one of those poor souls that will wander around the globe forever waisting his time in trying to baptize the non-believers ....
