OFS has been used to rebuild the record since awk was first invented
in the late 1970s.

As to "why?" I would have to guess that as OFS is used for output, and
most of the time the record is rebuilt in order to output it, that
using OFS made sense.

Additionally, as of 1987's "new" awk, when FS became it a regular expression,
using FS would make even less sense.

I hope this and the other answers have helped.

Thanks,

Arnold
