Since none of those assumptions are specified, you have no idea which of them will inexplicably change during a bugfix. You wanted that in cornflower blue instead, but now none of your settings are persisted in the backend. So you tell it to persist the backend, but now the UI is completely different. So you specify the UI more precisely, and now the backend data format is incompatible.

By the time you specify all the bits you care about, maybe you start to think about a more concise way to specify all these requirements…
