Giant TNT/bomb blocks for VANILLA MC

You know how when you're doing a huge project, like making a witch farm in a giant swamp full of water where you use tons of TNT, or say, when you're going netherite mining in the nether? 

I think that there should be a special TNT or bomb block that specifically aims to clear out a huge area, like a 50x50 block radius, or 100x100 block radius, in vanilla minecraft. Even 25x25 would honestly be better than the current smaller TNT blocks. It could be called a "Dirty Bomb" or something, idk. But it would essentially clear out this huge area. It would probably function like TNT when in water, but like how sponges can take out large amounts of water at once, there should be this block that's better than the basic TNT we're provided. With stronger bombs, I think that it would require less bombs, and therefore less lag - right? Because there's so many TNT blocks when doing huge projects and it can easily lag. To fix that, I thought along the lines of "what if there was a huge nuke bomb with a large radius for large areas?"

I know it's probably silly, but this would be a great addition to the minecraft community by far, especially for not only normal players who like to have fun with TNT and bombs, but also the really admired MC content creators who do giant builds that require lots of TNT for huge projects, and generally just really skilled builders who genuinely play worlds to build and make it their own and make it unique rather than just playing it and abandoning it a week later.
