Why do most modern luggages have grooves?

I was shopping for a new luggage and it took me ages before I could finally find one with a smooth surface. All hard luggages nowadays have grooves and I hate how they look. Do they serve a purpose other than aesthetics?

Besides structural support I feel that it helps with sliding and keeping the entire thing from looking scraped and scuffed as everything in the baggage system is slides and rollers
