Half of the obscure features mentioned required the author's massaging to make useful to himself. The history of these "solutions looking for a problem" is common, some guy reveling in a rabbit hole of his own creation, the only difference being that guy was old enough to have a gnu.org email address whereas the rest of us publish our dabblings on github as third-party packages.

This reminds me of the fading but ever present power of institutionalism. For probably good reasons we accord higher respect to the Tonight Show than some rando podcaster. But at least in emacs's case, there really is no quality difference between a "batteries included" mode and one off the rack.
