 # We depend on kotlinx-serialization as compileOnly.
 # If the serializers don't get used, the library works properly even without the
 # kotlinx-serialization dependency, but Proguard emits warnings about datetime
-# classes mentioning some serialization-related entities.
-# These rules should not cause problems: if a project actually relies on
-# serialization, then much more than just these two classes will be required,
-# so telling Proguard not to worry if these two are missing will not prevent it
-# from emitting errors for code that does use serialization but somehow forgot
-# to depend on it.
