The parameter `decoderFactory` of the static methods `ByteToMessageDecoderVerifier.verifyDecoder` do not need to be `@escaping`. I have made them non-escaping as part of `Sendable` adoption because we would otherwise need to think about if they should be `@Sendable` too. `VerificationError` is interesting, see the code comment for more information.

Can you clarify that the reason VerificationError already conforms to Sendable is that it's of type Error, which must conform.
