I have a library project I'm looking to get upgraded to 1.5 kotlin(targeting 1.4 api still). As part of that upgrade I'll be using kotlinx.coroutines 1.5.2 so I can use the ReceiveChannel.onReceiveCatching new goodness. But this project will be used by 1.4 people. Via the magic of gradle, they'll be upgraded to 1.5.2 coroutines lib running on 1.4. Is that kosher?

Not really gradle magic, just how transitive depencies are managed. Not sure about the details with gradle, but I think it goes wrong if they have a direct depency on coroutines.

It shouldn't be a problem, since new versions of coroutines are binary compatible with the older versions. That means the code compiled with 1.4 will work with 1.5.2.
I'm not sure about @ExperimentalCoroutinesApi though, so if they use it, it could be a problem

That is what I wanted to make sure of. 1.4 kotlin compilers using the 1.5 Kotlix-couroutines.

We didnt use any experimental APIs, and if anyone downstream did, well, they opted into it. 🙂
