PEERS NAMES is part of CONTROL FILELIST  which is peered to the BACKBONE sites
only. The backbone sites are very  clearly defined and registered. If you give
me the name of a site, I can tell you if it's backbone or not. But if it's not
a backbone  site, I can't tell  you whether it supports  this configuration of
PEERS NAMES/LINKSWT FILE  or suchlike. A backbone site is  by definition up to
date enough for me to know what it can take and what it can't take. Now how do
you  expect me  to remember  which release  of LISTSERV  removed this  or that
restriction, especially when I  no longer have the code to  check it out? Even
if I could  remember, how can I  implement this technically? I  can't create a
filelist peered with all 1.5f servers, one for 1.5g, 1.5h, and so on.
