1. Belly pans are a maintenance issue for one thing. Another thing is that with an already low sitting car the benefits may not be all that obvious.

A piece of conveyor belt material hung in front of the tires as shown and you might be able to pull off a Corvette type cooling arrangement when blocking the grille. I have no idea how much engineering GM puts into this, and it may not be something you want to do in your own backyard.

2. Grille blocks; back in 1983 I put some cardboard in front of my radiator on a 1976 short box Ford van, 6 cyl with three on a tree shifter. On a early spring day which got much warmer than expected the truck ran hotter than I would liked to have seen - I was helping a friend move and could not stop or I would have lost them. I ended up replacing the head gasket shortly afterwords. The van would not warm up on short trip winter days, and Michigan springs are anything but predictable. No grille blocks for me, not even in the winter - sorry.

Maybe modern engines with electric fans take to grille blocking much better than the old cars/trucks. I for one just don't care to chance it, and the GM Dex-Cool engine I have is reported to have coolant and possible head gasket issues if not properly maintained. I'd rather not temp fate nor take unnecessary risks. Once burned, twice shy.
