Comment (by eschnett):

 Yes, brevity is the reason for not using CCTK_INDEX. This would require
 {{{
 CCTK_GFINDEX3D(cctkGH, CCTK_INDEX[0], CCTK_INDEX[1], CCTK_INDEX[2])
 }}}
 or (in Fortran)
 {{{
 gxx(CCTK_INDEX(1), CCTK_INDEX(2), CCTK_INDEX(3))
 }}}
 which may lead people to not use these macros (or make them add their own
 boilerplate to introduce shorter names).
