================
Comment at: libcxx/include/__availability:145
+    // contains ABI breaking changes.
+#   define _LIBCPP_AVAILABILITY_FORMAT
+
----------------
Are there any feature test macros associated to this feature? If so, we'll need to disable the feature test macros when we disable the format feature (otherwise, the feature test macro will pretend that `std::format` is available, but one will get an availability error due to the attribute when trying to use it).
