Well, in the end your repeated good reasoning has prevailed:
I've committed a change (to R-devel; most probably in
time to be ported to 4.0.1 beta).
I think this implements the   recycle0 = TRUE   behavior you
have been advocating for,
in svn r78591  (2020-05-27 19:45:07 +0200)   with message

      paste(), paste0(): collapse=<string> always gives a string
      (also w/ `recycle0=TRUE`)

Best regards,
Martin
