A similar "track is component" scenario:

That certainly is a dirty trick! (But on a very tight budget it could
make sense).
So there are several use cases for treating copper as non-connecting:
* low value resistors
* fuses
* low value inductors
* aerials
* contacts for solder switches (eg SPDT in solder)
Similar to the last is a jumper location that is connected by copper by
default to be cut if an open is needed. Consider this to be a 1 bit PROM.
