Should EuiAccordion have a disabled state?

[myasonik]

Found this pattern in the wild where an accordion conditionally has data. If there's no data present, they're lightening the text color of the accordion's button but the accordion can still open and close showing nothing.

I think we should either add a disabled state to accordions or provide an example of a pattern to replace ones like this.
