I would agree if it was doing a whole disk.
A swap or scatch space on magnetic media got used alot back then.
Time sharing back then was having 16KW and swapping pages back and forth
from rotating media while reading or writing cards.

for the swap segments on disk would useful.

Well the CPU is the easy part. Now what about the front panel. :)
