Strap around battery compartment

I've noticed a lot of pics with a Velcro strap around the battery compartment. Is the battery door problematic or are people just doing this a precaution?

Precaution here. Will help keep battery inside compartment in case of spill.Handy when bike is on car rack to keep door closed.
