Hi Bastien,

Yes, that's what I thought. That makes sense.

No, and, honestly, I won't try, because I remember seeing that not
functioning for a very long time, certainly well above 1 year. And so
many things changed in my config (Emacs, Org mode) and in Org mode, that
I'm not sure at all to come back to a previously working state -- if it
did [1].

Well, here, it would be useful that ALLTAGS would really report ALL
TAGS... (even if it wasn't its default behavior)

Then, I won't.  But such a cleaning (in `before-save-hook') is not
possible, then?

Best regards,
