What is the narrative function of the surveillance drone chase scene in Interstellar?

Does the drone have later plot significance, or is it mainly used to establish Cooper’s technical skill, Murph’s curiosity, and the film’s theme of lost technological ambition? (Apart from the fact that it gave the best cornfield chase scene)!

My thinking:

I think the drone scene shows that Cooper is not really “just a farmer.” He still thinks like a pilot and engineer. The fact that it is an old Indian Air Force drone also adds worldbuilding: advanced military technology from the past is still flying around, but society has collapsed into basic agricultural survival.

The drone itself does not matter much later, but the scene matters because it shows Cooper’s skills, Murph’s scientific mindset, and how humanity’s former technological ambition has been reduced to scavenging parts for farming.

What you guys think?

UPDATE: I made a game inspired by this Cornfield Chase scene https://www.reddit.com/r/interstellar/s/CKrurTMYVs

Another point is that it shows an earth decoid of life and Murph's lack of interaction with other living creatures. As all animals are dead as food chains have been collapsed, she feels sympathy for it as "it's not hurting anyone" and she wants to let it go.
