Common with 16" wheel and 20" wheel bikes - and not unheard of with big wheel bikes.
There is more than one way to skin a cat. Dunno what it is you want to tote, but stepping away from panniers, there are rack bags, trunk bags, saddlebags, handlebar bags, bike packing luggage and an entire range of bags, baskets and mounts from folks like KlickFix. Nearly all are available with some sort of quick attach/disconnect.
