Perhaps here my lack of expertise shines most brightly, but would this
dummy tag modification (provided I have the Preferences->Store Tags
Inside Photos set) force _all tags_ to be written to all effected
photos?  My expectation is that it would merely modify the tag in
question (and thus not migrate the remaining tags) in order to not
introduce a performance regression (only change what changed rather
than re-write everything, but since I don't know how the metadata
works this is merely a guess).... but I'll give it a shot on a few
photos.  Attempting it on the whole collection might be a bit intense
(161Gb of photos.....) but if its this or nothing!
