Akka 2.7.0 is safe to port as it's Apache 2.0 too; we should not diverge
much, many changes in Akka are actually fine.
I will try to port the testkit-related things this weekend. I will spend
all my weekend working on the stream things, because I want the stream to
be great,
In case someone is building an MCP Server/Client with Pekko Stream.

And ZSTD is really needed and great, as the Pekko 1.3.0 is the last one we
support Java 8 , so I really suggest we contain all the features in Akka
2.7.0
