Since there’s a reified serializer<T>() that throws if no serializer is found, why isn’t there a serializerOrNull<T>() as well? I know there’s a serializerOrNull(KType), but as I understand it, typeOf<T>() relies on reflection and has performance implications.

typeOf<T>() is an intrinsic, what performance implications?

[ephemient]

it does require constructing kotlin.reflect implementation objects but it isn't runtime reflection

and that got caching added a while ago, https://github.com/JetBrains/kotlin/commit/fdd541c1e9cdccd6f96c49e24844f9b8450273a2
