 Some of these are **unsound**, which means they can lead
 to Miri failing to detect cases of undefined behavior in a program.
 
-* `-Zmiri-allow-uninit-numbers` disables the check to ensure that number types (integer and float
-  types) always hold initialized data. (They must still be initialized when any actual operation,
-  such as arithmetic, is performed.) Using this flag is **unsound** and
-  [deprecated](https://github.com/rust-lang/miri/issues/2187). This has no effect when
-  `-Zmiri-disable-validation` is present.
-* `-Zmiri-allow-ptr-int-transmute` makes Miri more accepting of transmutation between pointers and
-  integers via `mem::transmute` or union/pointer type punning. This has two effects: it disables the
-  check against integers storing a pointer (i.e., data with provenance), thus allowing
-  pointer-to-integer transmutation, and it treats integer-to-pointer transmutation as equivalent to
-  a cast. Implies `-Zmiri-permissive-provenance`. Using this flag is **unsound** and
-  [deprecated](https://github.com/rust-lang/miri/issues/2188).
 * `-Zmiri-disable-abi-check` disables checking [function ABI]. Using this flag
   is **unsound**.
