It does. From a language perspective. It is a "distribution", because at
the times BSD was developed, it was not a complete operating system. It
was supposed to be "added" to say AT&T System V to make it networking
capable etc.
The Linux people use the word "distribution" in a different context.

You can always have faster algorithm if it is not necessary to produce
the right answer.

Developers are not Gods. Developers have no clue on what system and for
what purpose you will use the software. All they may do for you is to
provide enough knobs for you to tune your system for your
hardware/application and also make sure that the system scales, when you
turn the knobs.
