As far as I know, it would be used when time stretching or pitch shifting a region of audio, changing the tempo of your song, playback with RealDrums, and harmony features. It wouldn't have anything to do with changing the pitch of MIDI notes.

What are the dates of the Elastique files in the pt\data\libx64 folder?

Checking the Elastique setting in the audio settings window is probably good advice, and shouldn't have any negative impact. If you DO time stretch audio / change tempo, you could get better results if you enable that setting prior to doing so. Another thing to try is Edit | Track | Consolidate.
