Aha, that was the answer. Apparently installing Okular adds this bit of 
silliness into /etc/mailcap:

application/vnd.oasis.opendocument.text; okular %s --icon okular -caption 
Okular; test=test -n "$DISPLAY"

... which I find now has also been reported to Debian as a bug:

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=857443

I still think it's insane, but at least now it's clear where the insanity lies: 
with Okular's inflated sense of self-importance :D

But, what I still don't understand is, after adding an ODT entry to 
org-file-apps, why did org revert to querying mailcap...?

Value: ((auto-mode . emacs)
 ("\\.mm\\'" . default)
 ("\\.x?html?\\'" . "/usr/bin/firefox %s")
 ("\\.odt\\'" . "/usr/bin/libreoffice6.0 %s")
 ("\\.pdf\\'" . "/usr/bin/okular %s"))

Original value was 
((auto-mode . emacs)
 ("\\.mm\\'" . default)
 ("\\.x?html?\\'" . default)
 ("\\.pdf\\'" . default))

... this has exactly zero effect. Org ignores the odt line here, where I would 
expect an org-specific preference setting to override the system default.
