shouldn't these become async as well?

[filintod]

the runtime and the client are separate entities, as you have seen in your PR, so the client can be async or not

[passuied]

@filintod looking at the examples you've added I think you would benefit from either waiting for my PR to be merged or merging that PR into your branch.
Unfortunately mixing sync and async has been leading to deadlocks/blocked thread when we tried to use the sync WorkflowClient in async methods... We had to use run_in_threadpool() to avoid this issue...

@passuied I'll wait for your PR to be merged, it complements this
