this is satire, right?

This is already how busybox works. These examples are taking it to a more extreme level but it's not _that_ crazy.

  AIUI, on Windows, pip (via the vendored `distlib`) also makes stub executables that work this way to implement the "entry points" defined in installed wheels. See: https://github.com/pypa/distlib/blob/master/PC/ReadMe.txt https://github.com/pypa/distlib/blob/master/PC/ReadMe.txt

It may be a bit uncommon, but it's not at all new. For example, on a Linux system I have, there are several files in /usr/bin that use hard links to refer to the same file (inode) by different names: bunzip2 / bzcat / bzip2 gunzip / uncompress unzip / zipinfo pigz / unpigz pkg-config / x86_64-pc-linux-gnu-pkg-config perlbug / perlthanks Use ls -li to show the inode number for each file or directory. For example: $ ls -li /usr/bin/{bzip2,bunzip2,bzcat} 23069197 -rwxr-xr-x 3 root root 39144 Sep 5 2019 /usr/bin/bunzip2 23069197 -rwxr-xr-x 3 root root 39144 Sep 5 2019 /usr/bin/bzcat 23069197 -rwxr-xr-x 3 root root 39144 Sep 5 2019 /usr/bin/bzip2

  That's more a case of providing the distinct "APIs" ( bzip2 , gunzip etc) to userland / scripts, while the implementation for all is just one binary; than it being "Configuration via name..." Somewhat similar to how busybox does its thing.

I'd say "kind of", because it's ridiculous on the surface but could be a handy trick. If only to be aware that an executable gets told its own name.

I have used that in a project of my own[0] for convenience (avoid duplicated code), but it is uncommon, yes. I truly think it should be avoided in general, especially when what you actually want (in OP’s article) is a config file.
