I can't use sequence { } with abstract suspending functions, because StreamingCmd has to inherit from CmdBase and so can't inherit from SequenceScope

flow { }?

and while I can get over having to pull in kotlinx.coroutines for something as basic as a non-@RestrictsSuspension sequence builder, I do still want to keep the interface compatible with a non-suspending base, meaning I can't just stick Flow or ReceiveChannel as the return types.
