Oh, yes! Exactly that behaviour is what I had wanted. Thanks, Nikos.

That reminded me to re-read the option modification section, in
particular ...

  -+  Followed by one of the command line  option  letters  this  will
      reset  the  option  to  its  default setting and print a message
      describing the new setting.  (The "-+X" command  does  the  same
      thing  as "-+X"  on  the command line.)  This does not work for
      string-valued options.
  ...
  -!  Followed  by  one  of the command line option letters, this will
      reset the option to the "opposite" of its  default  setting  and
      print  a message describing the new setting.  This does not work
      for numeric or string-valued options.


... so sending text to "less -+S" via pipe worked as expected.

And, that stalled the creation of vi(m)-as-pager until some later
date. To that end ...
