DOS footprints?

[Sam Ewalt]

While poking around various DR-DOS sites today I was struck by the many
varieties of DOS available and I'm wondering if there might be advantages
for running Arachne with some of these other variants--like perhaps
earlier versions with a smaller footprint. Or would you gain something
there only to lose out better memory management with latter versions?

Comments from those with expertise would be appreciated.
