This allows developers to use Dart 3 sound null safety with packages that have
been migrated to 2.12 null safety without needing a second migration.
Note that this only applies to code that
doesn't depend on Dart 3 breaking changes:

* Several historical core library APIs have been removed; for details,
see the GitHub issues [#34233][] and [#49529][].
* The historical language syntax for default parameter values
([#2357][]) has been discontinued.
