The Micromonolith was an early version of Polylith and the blog post was written by me.
At that time we hadn't introduced the interface concept and the codebase
was something between a Monolith and a Polylith, but with benefits like
being able to work in a single REPL.
When we turned the components into decoupled and reusable blocks of code
(by introducing interfaces) we also changed the name to Polylith.
We didn't come up with all inventions from day one.
It was gradually improved and began with the Micromonolith.
