You make some excellent points.
Anecdotal evidence, particularly when it is frequent, usually has some substance and often more than the anecdotal evidence alone would suggest.
Pilots dont like having to file (me included). If I were Stansted I would want to do something about it, but you are correct, the answer is to file so the CAA can judge the full extent of the problem.
Your comments on CAT on a flight plan are totally valid. Never the less there is often a regrettable distinction between CAT on a FP and GA on a FP in terms of when they are "dumped" outside the system.
