What are the things you used the Elegy of the Deep on, that didn't do anything, that you wished did something and or hope/think might do something after future updates?

Surely something will be done with Shakra's master one day, right?
I also tried to play the song at the remains of Phantom, hoping that I could conjure the memories of when the grey Phantom was still freshly white instead of grey, for however brief that period of time might have been.
