I think perhaps I'm seeing the converse of #26: I use PascalCase for my constants, and the plugin considers erroneously them to be components. An example that will trigger the rule:

export const SomeConstant = 42 // ✗  [eslint] Fast refresh only works when a file only exports components ... 
export function someUtility() { return SomeConstant }

If I change that the capitalization to screaming snake, it passes:

export const SOME_CONSTANT = 42 // ✓
export function someUtility() { return SOME_CONSTANT }

OK, I guess PascalCase is not the preferred convention here. But is there any global setting I'm missing that could easily prevent such constants from being flagged? (Using eslint-disable-next-line is more distracting than it's worth; if I have to do that I'll probably just switch to screaming snake, but that's not my preference.)
