Scrutineering is not a declaration of legality, it's just declaration that the scrutineers are happy that is appears to conform to the rules and they're happy that it's safe to compete.
The car is checked by the scrutineers. If they find anything that is against the rules, they refuse to allow the car to race. If they allow the car to race then they consider it complies with the rules. Ergo, it is legal.
Now, a higher power can deem it illegal later if it is protested. This is similar to an appeal in a court of law. Someone is found not guilty by the lower court. At that point they are innocent (they have not broken the law - their actions were legal). If that decision is appealed to a higher court, then they might later be found to be guilty and punished (their action has now been considered to be illegal).
At the moment, Mercedes's wheel design is legal because the "lowest court" (the stewards) have said so. There is no argument here, it is legal.
If someone appeals to the FIA in the form of a protest, then the higher court may decide that the stewards were wrong. At that point the wheels would be illegal. But at the moment, that hasn't happened so the wheels are legal.
If you are more fortunate than others, build a larger table not a taller fence.
