Looks like I spoke too soon. Mappings can actually be removed at runtime, one such example is `Windows.SPI.HighContrastColorScheme`, which is only available if `Windows.SPI.HighContrast` is `true`. This doesn't change the `ChangedValue` implementation, and there are tests that cover the key removal scenario. ------------- PR Review Comment: https://git.openjdk.org/jfx/pull/1014#discussion_r1319364873
