I would argue that there's no reason to continue misspelling "lead" as "lede" outside of a context where you are worried about conflating the "lead" paragraph with the "lead" piece of metal which was used as a spacer between words in a Linotype machine

Does it still count as misspelling when "lede" is in the dictionary (Merriam Websters & Cambridge & Oxford)?
Pretty sure it's just a word at that point, right?
It's not a misspelling, it's jargon. FWIW I prefer it and I think it's valuable to preserve in part because people who dig into it a bit learn about the history of the term and practice of putting publications (especially newspapers) together.
