Yes, of course. But by the time it was invented the memory size of
typical microcumputer systems was usually just a few kB, and default
serial speed was often 1200 bps, maybe even 9600 bps.
It was good enough for that purpose. S-Records were not invented to
download megabyte-sized images of Unix systems...
If you feel it's slow and clumsy then just don't use it. Disable it
from the configuration. Use Ethernet, and enjoy the speed and ease of
use.
