Basic Static Block
Most of the articles, comments, and GitHub issues in the Gutenberg community from existing block developers have settled on the conclusion that Static Blocks should be used sparingly and only for fairly basic blocks that won’t change.
A number of people recommended only using Static blocks for those that correspond with actual HTML elements like <p>, <ul>, or <button> and to use Dynamic blocks for any block that represents a component with a more complex markup structure.
As such, we can revisit the creation and best practices of Static Blocks should the need arise in the future.
