Goes back to the usual 'spirit of the rules', FIA state there's a fuel flow limit put in place and state how it gets measured. Team comes up with a way to pass the test put in place (all fuel going to the engine passes through the flow meter and the flow rate never goes beyond the set threshold).
Similar story to the Red Bull flexible wings, they were designed in a way to flex beyond what the FIA deemed fair, but they passed the static load tests that defined the regulations so there was nothing that could be done.
Obviously in this case it's all a bit more hush-hush as neither the FIA or Ferrari are making the findings public. I am a bit confused as to (and again, I'm assuming last year's Ferrari engine was of questionable legality and they've since changed that to ensure it's clearly legal) how this will be enforced. Normally in cases like this the regulations are re-written (or added to) to add clarification that would mean whatever was previously bending the rules is now out-right breaking them.
Considering the teams are all pretty miffed that neither Ferrari nor the FIA are releasing the findings of the investigation, and have access to the regs, you have to think there's been no amendments made. So why would Ferrari change the design?
Didn't recall hearing anything about that at the time (or since, for that matter) but I guess that falls in line with what I was saying above. Though maybe I was wrong about it going to a holding tank of sorts, can't see any reference to that.
Edit 2 - Actually, I do recall Verstappen's comments on Ferrari's drop in pace "now that they've stopped cheating", so I guess that was well known.

Apologies for the lengthy non-answer.
