should be allow specifying a DispatchQueue per registered item?

[weissi]

Often, sub-systems won't be thread-safe so we rely on start & stop being called from the same thread. That is achievable with Configuration however only per Lifecycle and not once per item. What if two separate items rely on being each started/stopped on their own queue?

[weissi]

Not sure if absolutely necessary but we should at least have an "API hole" to plug this in in a subsequent release.

Since we just changed the whole package to use a new Structured Concurrency approach, I would like to close this issue. @weissi Is that fine with you?
