I don’t think this is true for several policies used in bitcoin core. Example: `dustrelayfee`

```C++
/** Min feerate for defining dust.
 * Changing the dust limit changes which transactions are
 * standard and should be done with care and ideally rarely. It makes sense to
 * only increase the dust limit after prior releases were already not creating
 * outputs below the new threshold */
static constexpr unsigned int DUST_RELAY_TX_FEE{3000};

```
