In a sense the simplicity of SLS is a trap: immediately when you need to move past the synchronous lambda invocations via API GW use case (caching, service integrations, step function workflows etc) you need to either fall back to plain CloudFormation or rely on third party plug-ins with possible problems with maintenance, quality and feature-completeness. This makes it a difficult choice to recommend beyond simple use cases.

Yeah this is one area it really struggles. I built a harness (using SST, actually!) for things like step functions, background jobs, cron-ed tasks that I'll try to open source once I clean it up a bunch.

I kind of see that as an unforced error on SLS's side as well; AWS EventBridge is pretty simple and would make those types of workflows possible, but the integration with SLS is really rough.
