Oh! Something interesting I noticed when watching the G Gundam parody again.
When Cadance and Shining Armor perform the big love-powerd shield wave thing, take a look at Cadance's mane during the whole sequence. For that short time, it
flows, much like Celestia's mane. At one point, even her tail flows. However, it settles back into a solid shape when the spell is over and they settle on the ground.
So, the flowing mane is definitely an indication of power. However, Cadance is younger than Celestia or Luna, and hasn't reached
full maturity yet. It's only in moments like that that her mane flows.
I think the best analogy I can think of is to think to
Dragon Ball Z. It's like the golden hair of the Super Saiyan state. Meanwhile, Celestia and Luna are like Goku in the Cell Saga: they're powerful enough that they're in this powerful state at all hours of the day.
