To me it is an issue, since I have some tags that I have been using for some underlying organizing scheme.
I use and populate these tags only on specific tracks, with a restricted list of words/descriptions.
My player/manager uses some formulas to check these tags for presence and these specific contents.
Such a scheme will be severely messed up when Picard decides to create and write these tag frames when they are not present in a track.
(and that is how I found out about this unwanted behavior)
Previously I assumed that the ‘add to preserve tag’ feature saved me from such troubles, but it’s now obvious to me that it doesn’t.
I’ll now try to find the tracks that have ‘unwanted’ information written to them, and remove it again.
Of course there are ways in which I can now try to circumvent these problems in the first place, but an option in Picard to prevent it creating specific tag frames through it’s UI would be very welcome.
