LSB 3.2 Core 20.3 [1]
says:

  Default-Start: run_level_1 [run_level_2...]
  Default-Stop: run_level_1 [run_level_2...]

      which run levels should by default run the init script with a
      start (stop) argument to start (stop) the services controlled by
      the init script

      For example, if a service should run in runlevels 3,4, and 5
      only, specify "Default-Start 3 4 5" and "Default-Stop: 0 1 2 6"

That seems fairly clear that it's supposed to control the default.
I don't know whether any distros automatically honour these settings
but I wouldn't be surprised if some of the fancy new parallel init
systems did.

You are quite right.

Ian.
