Works very well for me. I have some pretty complex configurations and they're all done declaratively with a bit of template logic. I think it's pretty rare to need a custom module (not that it's hard to write one). Ansible is 100% intended for configuration management. Configuration is by its very nature declarative, so in any case if you were doing a lot of custom procedural code for configuration you're probably doing something a bit wrong.
