OK, today, before trying the steps suggested in the previous messages,
I did an update. FWIW, this is what came:

In any event, now with DMO repos, apt only want to remove 11 packages
(same as without) without any action on my part:
The following packages will be REMOVED:
kde-style-breeze-qt4 libavcodec58:i386 libavutil56:i386
libfaudio0:i386 libmfx1:i386 libomp5-7 libswresample3:i386
libwine-development:i386 pylint3 python-logilab-common wine32-development:i386
I could tell that I could let kde-style-breeze-qt4,libomp5-7,
python-logilab-common and pylint3 go, so I removed them. I still see
some of the DMO packages marked to be removed (libavcodec58:i386,
libavutil56:i386, libmfx1:i386...), but I assume is the usual Sid
thing where you just need to wait for new updates to come to get
resolved. (I can see that libmfx1 wants to go from 1.25-dmo1 to
19.2.1-1 (from Debian's official repo), for instance.) Let me know if
I am wrong about just waiting. Otherwise I think the issue has been
resolved.
Thanks all for your help!
