Both Gmail and my MUA (notmuch) showed the message as addressed only to
me, but now that I examine the raw headers I see a Newsgroups: line.  I
guess you sent the list copy via NNTP instead of email?  In any case, I
didn’t notice it.  Sorry.

Yes.

OK, I’ve done some more investigation.  By default, minted uses
\newfloat from the float package to create the listing float class.
This does not set up the caption integration.  OTOH, adding the newfloat
option to minted uses \DeclareFloatingEnvironment from the newfloat
package, which works.  IOW, replacing the relevant line in your MWE with
the following makes it work:

\usepackage[newfloat]{minted}

I’m not sure how that should be integrated in the picture – perhaps org
should recommend (require) this invocation of minted.

But this is an implementation detail of minted, and could change in a
future release.
