Modular connectors as universal easy-to-crimp connectors even for motors is not a really good idea. I've seen them on various devices and the contacts are really only designed for signals anyway.
I prefer the modular screw terminals that you can plug in, especially the more compact 3.5mm variety and they come in all configurations and make it trivial to wire a cable in the field, all you need is a screwdriver. Although they are more expensive it seems to me that trying to use modular connectors because they can be handled in the field is creating a situation where the damage they cause by wrongly connecting them cannot be handled in the field.
Circuit protection is one thing but prevention is better than a cure. Don't let those connectors get mixed up in the first place.
