I did a zipper dup to TW 20201223 and kdepim3 got removed. Would anyone here know the reason? Relevant history is appended. I wonder if it was because I didn't add --no-allow-vendor-change? I had locked out Plasma/KDE kmail from install by making it taboo, in the past this has been sufficient to ensure kdepim3 remained the desktop mail client.
