Formula 1 teams were informed in the wake of the Chinese Grand Prix that rear-view mirrors could be mounted onto the halo for better visibility, and Ferrari was the first team to introduce a revised approach in Spain.
Jean Todt has said that he thinks Ferrari's Formula 1 "quit threat" will eventually recede.
But FIA president Todt lashed out at the drivers, saying there are already structures in place so that they can have a say.
Ferrari boss Sergio Marchionne took a negative stance on F1's 2021 regulation blue print when it was tabled past year to teams, saying the draft called into question the sport's DNA, a state of affairs which could entice the Scuderia to leave Grand Prix racing.
"There are several reasons for that, and one of them is that the sport is very important for them".
The FIA felt the arrangement broke the rules, and while they allowed the Italian team to keep it on the vehicle for the remainder of the weekend, they told them to remove it for the upcoming race in Monaco.
"Whilst the FIA accepts that teams will legitimately design the mirrors, housings and mountings to minimise any negative aerodynamic effects they may cause, we believe that any aerodynamic benefits should be incidental, or at least minimal", said the FIA in a statement.
But Todt was also keen to stress that the new rules must suit all teams, including potential new ones, and not just Ferrari.
"More than half of the teams are in difficulty, and that's not good for the premier discipline of motorsport".
"I don't want to now read the headline "Todt contradicts Vettel", but that's what you'll do", said Todt. In addition to the likely introduction of a budget-cap, F1's managers aim to scrap the onerous MGU-H element of the current power unit.
And world champion Lewis Hamilton said: "We should make the decisions". "We are well on the way with the engine regulations", he added.
