we should break down and MR into "Blocks"

There’s several benefits to splitting code into multiple packages, whether it be a library, micro-services or micro-frontends.

Suppose that the validate task was getting quite complex and bloated. When writing “normal” Ruby, you’d break up one method into several. In Trailblazer, that’s when you introduce a new, smaller activity.

Both of these make it difficult to code-split the top of the tree (where the state has to live) from the leaves of the tree (where the state is used).
