Agree. The conflicting thing which kind of binds FIA to Pirelli's fate, and the point at which I do agree with you and Pirelli is that, is that it is shame that the standardized tire pressure monitoring system TPMS (in race) was pushed back with the 18 inch wheels.
I can imagine that Pirelli kind of is annoyed with the FIA for not giving them enough FP running, or in race pressure data, or tire tests, to be able to really conclude anything useful, so we are left with their useless statement and these new 'rules'/'actions'.
It smells to me like another case of "we just have to do something!!!" with a large emphasis on the "something"
