The 2013 StackExchange post 1 describes what is now commonly called an "archetype" based ECS architecture that was implemented as compile time archetypes in the author's open source project in Feb 2018 2. A similar ECS model was described later in the June 2018 patent filed by Unity 3 and active since 2020.
It's useful to bring visibility to the issue for the inevitable patent trolling that will occur in the future.
