It's a fun troll, good for a laugh. The author doesn't intend it for serious use. But you knew that.
I didn’t know that nor do I find trolling to be “fun”
Has anybody written an emacs clone in emacs yet?
And if you want a small init (for very custom systems or containers) look at tini
I find BusyBox init perfectly acceptable and small. I use it extensively as init for lightweight containers. It supports just enough init to handle complex or simple config.
Does tini offer something better? On quick glance it seems rather limited.

That is the point. It does just what we need with a minimal amount of code.
For systems that are small but not tiny, one could consider runit or s6.
The init wars were fought nearly a decade ago. To kids these days, systemd is init.
More than two decades. At the time, SysV init was the bloated and bsdinit the lean, "do one thing" one.
Something needn't have 1:1 feature parity to replace something else. I recently replaced my car with a motorcycle.
