A few common uses for that cage location...
With fenders it stays cleaner.
Fuel bottles can go there when camp cooking for touring.
Bulk water bottles for water storage(to then be poured into a drink bottle) go there.
Whichever is selected, a velcro strap is usually helpful to both ensure the bottle doesnt pop out AND to keep the cage from fatiguing. Bottle cages werent designed to support weight with the front lip down and that stresses the cages, so a strap helps reduce downward stresses from bumps.
