Disagree. The US legal system runs on the principle that unless something is forbidden by law, it is permitted.

There is nothing in the Constitution forbidding delegation of implementation decisions from Congress to Executive. Therefore it is legal.

And if for some reason this is the one exception to the way our legal system works, where the lack of express permission means it is forbidden, isn’t it odd that the courts have the power to make this decision despite not having a written mandate.

This is absolutely a power grab, with the intent of “breaking the administrative state”, as Steve Brannon promised. It is not possible for 438 people to legislate the implementation details of every policy in the entire country on an ongoing basis. This is basically Make Rivers Flammable Again.
