I wouldn't underrate the technical issues. To really make it work, you've gotta get the tooling right, so you're not writing and maintaining plumbing (logging, tracing, runtime config, networking, deployment, API layer, repository, etc etc) for every single microservice, all in their little bespoke ways. I once decommissioned a microservice after noting that the LoC of all its plumbing and config outweighed the actual logic 5:1. Pushing that plumbing to the background, so it can be managed as a cross-cutting concern, isn't so easy.
