Thank you Corey!

Yup, I didn't actually manage to read that in the man page.  Bummer,
although that conflicts with the following from section "GENERAL
OPERATION":

  Each  server name that you specify following the options on the
  command line will be queried.  If you don't specify any servers on
  the command line, each 'poll' entry in your ~/.fetchmailrc file
                    ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  will be queried.
  ^^^^^^^^^^^^^^^^

Back to cronjobs, either that or maintaining two separate fetchmail
config files + pid files, etc.  :/
