Purpose uncertain. I guess it's slightly better, maybe. The move of the sws/zimg options from VO opts (vo_opt_list) to the top-level option list is tricky. VO opts have some helper code in vo.c, that sends VOCTRL_SET_PANSCAN to the VO on every VO opts change. That's because updating certain VO options used to be this way (and not just the panscan option). This isn't needed anymore for sws/zimg options, so explicitly move them away.
