The Dutch artificial island 'Flevopolder' is ~970 square km. So, I wouldn't say giant when there is an artificial island that has a 373x larger surface area.

It is still a very nice project nonetheless!

But that’s a polder made mostly by building dykes and draining the land rather than raising up the ground level across 970 square km. Flevopolder is about 4m below sea level.

I think the plan here is different and will not be done by building up dykes and draining the area inside.

Yeah replacing water with air is a big project but replacing water and air with land is bigger.

Even IJburg (https://en.wikipedia.org/wiki/IJburg) is 2.2km^2.
