   direct dependencies, but rather non-trivial results of other configs missing. Then
   look for any unset symbols and handle their reverse dependencies.
   Examples of EXCLUSIVE_GROUPS usage:
-  - MBEDTLS_SHA256 job turns off all hashes except SHA256, however, when investigating
-    reverse dependencies, SHA224 is found to depend on SHA256, so it is disabled,
-    and then SHA256 is found to depend on SHA224, so it is also disabled. To handle
-    this, there's a field in EXCLUSIVE_GROUPS that states that in a SHA256 test SHA224
-    should also be enabled before processing reverse dependencies:
-    'MBEDTLS_SHA256_C': ['+MBEDTLS_SHA224_C']
   - MBEDTLS_SHA512_C job turns off all hashes except SHA512. MBEDTLS_SSL_COOKIE_C
     requires either SHA256 or SHA384 to work, so it also has to be disabled.
     This is not a dependency on SHA512_C, but a result of an exclusive domain
