I'm writing a plugin to do Keyword consolidation. However, after removing all photos from obsolete keywords (removing keyword from all photos that have it), I still can't deep-six the keyword. Its not that big of a deal, since I can just log a list of obsolete keywords for the user to delete manually, still - this function is missing: catalog:deleteKeyword.
Wow. Nearly 7 years and we still can't delete a keyword? I think my plugin goals have just been squashed. They've added the Metadata->PurgeUnusedKeywords command but it certainly isn't user friendly for a plugin to leave dead keywords behind.
