That's fun.

You didn't even beat wikipedia to the punch. They've had a nice page about minifloats using 6-8 bit sizes as examples for about 20 years.
The 4 bit section is newer, but it actually follows IEEE rules. Your joke formats forgot there's an implied 1 bit in the fraction. And how exponents work.
Interesting! I have been using integers or f32 for that. What was the use case specifically? Did you write a software float for it? I remember writing a `f16` type for an IC that used that was a pain!
