I suggest the replace required block (netherrack) to campfire block

As the campfire block is another tile entity, this would lead to the cooking pot mechanic requiring more tile entities. Plus, signs on campfires would not work as well as on a netherrack block.

From a performance perspective, this would be significantly worse than the current design

maybe then it would be possible to have a separate mechanism? for example, to open a campfire like a chest, put raw food and coal there for cooking
