Hi! Are io.ktor.util.collections.ConcurrentMap and io.ktor.util.collections.ConcurrentSet considered public API (in terms of can I safely use it in my network module which already has dependency on Ktor)? I see only comment Please do not use it. on ConcurrentMap (and no comment on ConcurrentSet ), but they both have public visibility and no InternalAPI annotation.

Which platforms do you target?

I'm developing multiplatform mobile app with Android and iOS targets

As I can see, the implementation of the ConcurrentMap is delegated to the ConcurrentHashMap on the JVM platform. On the POSIX targets, each operation of the ConcurrentMap is synchronized with a lock and the LinkedHashMap is used as a delegate. The ConcurrentSet uses the ConcurrentMap under the hood.
I think it's safe to use these classes as long as the implementations fit your requirements.

Yeah, the implementation is fine, I considered using Ktor's implementation or copy-pasting something like this into my project if Ktor's maintainers consider this as an internal API.
Thank you!
