As someone who only uses default kde settings: no!
This is the type of change I wouldn't notice until a default created UX friction, and not being able to fix that change would drive me away from the DE. Having the option to hack at something means i can use it for much longer without concern.
Unfortunately (or fortunately?) this appears to be untrue.
Polaris is a cluster of stars formed about 2 billion years ago. Sharks originated about 450 million years ago.
One star of Polaris (Aa) appears to be 50 million years old, but it seems likely due to a collision of stars which added mass to it.
