fs.exists, fs.existsSync - why are they deprecated?

Question

I noticed that the official node documentation says something startling about fs.exists:

\"fs.exists() is an anachronism and exists only

Answer 1

There is no need to use fs.stat(), because fs.existsSync() has not been deprecated.

https://nodejs.org/api/fs.html#fs_fs_existssync_path

fs.existsSync(path)

Added in: v0.1.21 path | Synchronous version of fs.exists(). Returns true if the file exists, false otherwise.

Note that fs.exists() is deprecated, but fs.existsSync() is not. (The callback >parameter to fs.exists() accepts parameters that are inconsistent with other >Node.js callbacks. fs.existsSync() does not use a callback.)
