Is there a reason

broadcastIn

for

Flow

is not

@ExperimentalCoroutinesApi

but still

@FlowPreview

in 1.3.0-M1?

It is not clear yet if broadcast channel are there to stay in the long term or if shared flows will replace them.

@elizarov In general, what is the difference between

FlowPreview

and

ExperimentalCoroutinesApi

? Are there actually stronger guarantees/expectations around the latter?

Yes. Experimental is generally belived to become stable in the future, unless serious problems found. Preview is just a pure preview. Will highly likely change
