navindra I was actually wondering about that too. On an upright, the internals are hidden away most of the time, but on a grand, they are often fully exposed... so why not do the rope trick on grands? I don't see the rope on my Estonia either.
My guess is a rope is non-optimal from a sound perspective - it's a loose baffle whose only sonic effect would be to absorb vibrations from the soundboard that would otherwise be transmitted as tone? I'm sure the effect is beyond minimal, but in the world of pianos, that'd be enough for some manufacturers to say "no way," right?
If an upright piano costs $10000, how much would it cost if they didn't bother with all these cosmetic touches? $5000?
I've seen some insane details inside old uprights, including gold, paint, veneers. My guess is it's part theater, part "we cut no corners at all, even the parts you can't see are finished."
Same with grands, Fazioli and others have some incredibly nicely finshed/varnished undersides and beams, that you'd never see without crawling under your piano (mine is the standard matte black for everything other than the soundboard).
Pianos aren't solely instruments, they're furniture and luxury items and symbols of wealth and prosperity, and I guess it makes sense to have the same kind of "jewel movement" thinking like in luxury watches, right?

That's a gorgeous veneer, birds eye? I really love pianos with a light/airy visual interior. Is it Hailun 151 by chance?
