The world is vast, and I doubt that every mechanical engineer has studied steam engines, and that it makes a difference in the end.

Most modern programmers don't learn COBOL60 or Commodore BASIC. Modern mathematician very rarely study writings of Euler or Gauss; even 50 years old math books may be hard to grasp for modern students.

I agree that using a simpler tool for educational purpose is useful, but since SysVinit is obsoleted almost everywhere, it made sense to drop it. LFS could have chosen a simpler init than the domain standard, like runit or s6-init.
