Two issues arise:
1) I haven't seen the wiring diagram, but wiring switches in parallel
might result in the possibility of a short circuit. There are ways to
do multiple reversing switches that don't do this.
2) Maybe they're worried about remote control devices that can injure or
kill, so they discourage their use. The factory version might have
interlocks, etc. to make it safer.
