On unwrap a perfect square, it adds an innecessary margin #6

Yeah, I sort all UV islands with a 1px margin to avoid bleed.

It really depends whether this is "unnecessary" or not. Depending on your texture wrap settings, you could also have bleed around the image boundaries.

My assumption is that 3D Pixel Art textures are tiny anyway, so who cares if there's a little extra margin here and there.

If you add some seams you end up with this, which is totally fine, IMO.

The plugin doesn't really focus on efficient packing of islands. If you want efficient packing, you can always use some kind of stand-alone texture packer like SpriteUV 2. Because if you're really trying to squeeze performance, it makes sense not just to pack each individual texture efficiently, but to combine all textures into an atlas.

Can be added as a parameter at least? it would be really cool 🤔
