A definition is given as literally the first paragraph of the post.

> Mimicry is when software X reimplements at a higher level a core feature of software Y. The produced facsimile has some, but not all, of the same properties, enough to “look like” it’s the same thing but missing many of the nuances. This exists in every kind of software. One language can mimic another, a library can mimic a language, a database engine can mimic a product, etc.

I don't see how your question even fits into that definition.
