New description:

 The &&& operator does not distinguish between Z and M values,
 see this:
 {{{
 WITH v(i,g) AS ( VALUES
  (1,'POINT(0 0)'::geometry),
  (2,'POINTZ(0 0 1)'), ---- X (wrong)
  (3,'POINTZ(0 0 0)'),
  (4,'POINTM(0 0 1)'), ---- X
  (5,'POINTZM(0 0 0 1)'),
  (6,'POINTZM(0 0 1 0)') -- X (wrong)
  )
 SELECT i FROM v WHERE g &&& 'POINTM(0 0 1)'::geometry;
 }}}
