I think all the PU manufacturers do.
The idea is that Ferrari will still be significantly behind all the other PUs, which lead to them blocking it. Not that they are being spiteful.
Also with Renault planning to release a whole new PU for the beginning of 2022, the idea there is there They've gonna look for alot of leeway to make changes to fix reliability features. That almost always lead to introducing realibility change that improvement power. Then bickering about cheating.
