As Barman1 says, it's just convenient to carry a modern one handed opening knife.
The ability to hold onto what needs cutting at the same time I can quickly open my knife, works best for me.
In 33 years of forestry work I carried a folding knife everyday, first a Buck 110, and then a Spyderco Endura for the fast one-handed opening ability.
I'm now a retired old fart with arthritis and carpal tunnel syndrome, so I switched to a flipper, ZT 0770 for rapid one-handed opening.
So, yes it does matter to me for my EDC folding knife. When fishing / boating I only carry fixed blade knives for cutting line, bait, and cleaning fish.
