Thank you for your thoughts Yan.

We’ve recently migrated from Circle 2.0 to CodePipeline and we do run single scripts per build step as you describe.

Interesting to know that Serverless framework migrated from single to multi stack! We didn’t look into Serverless too much as we wanted to understand the low level AWS resources as well as possible, and just using SAM proved to be a challenging enough abstraction in some respects. Also our Lambdas are written in Go and I’m not sure if the Serverless framework plays well with that yet (i.e. shim-less integration).
