I don't have it in my heart to get into an argument online, but Spottedleaf's Heart (2017) came out like almost a decade later from Bluestar's Prophecy (2009).
I just don't care about it, it is a pointless retcon, that reframes Spottedleaf, and Thistleclaw's entire character arcs.
I don't think anyone should be forced to interact with it as canon if they don't want to.
