Look, I'm not claiming it would be a good idea. But if you're the type who wants to wear a parachute despite it being non-standard, and you've got the skydiving rig taking up space in your closet, and would have to pay extra for the usual emergency parachute -- maybe you don't have a ton of money (after aircraft maintenance anyway), or even think the skydiving rig is "better" in some ill-specified way -- do you really think it's impossible someone would just use what they have?
Like, if a high-end gaming PC is what you have on hand after upgrading, why not give Gramps a computer that will maybe take a little longer to bog down?
No one would want to sit on a sport parachute pack for funsies. They’re bulky and the cockpit is small. Even the acro chutes are slightly bulky and uncomfortable in a light aircraft cockpit. You wear them when flying acro; no one I know wears them when flying their aerobatic aircraft on a random trip.
