How does the FIA intend to police this TD? Sure it can look at the drawings but them then saying “I think this will flex” isn’t gonna cut it. How will they prove that any designs are taking advantage here?
Requiring several 10mm thick aluminium alloy braces (similar to a rear wing mount) to hold the front wing flap elements in their respective positions should do the trick.
As it is, it seems teams aren't even
trying to make their front wing elements rigid!

I think I get number 3 but if I’m right with what I think how on earth would that be simulated in CFD?
CFD normally doesn't include elastic effects, however they would know what the geometry is supposed to be at different levels of load/speed and have different models for different speeds. Having different models in their system to account for different levels of flex would be a
dead giveaway that a part is deliberately designed to flex!
Though I suppose you could couple CFD with FEA to include elastic effects, i.e., with this much load it deflects this much? But the CFD analysis itself is still going to be time-average with a fixed geometry to be tractable to solve for an object like a Grand Prix car, and
not include fluttering (or porpoising) effects!
