I was thinking about that a bit today.
The old 2 prong freewheels have pretty tight clearance, so they probably don't need an extra seal.
On the other hand, the splined freewheels have a little greater clearance, so replacing seal is probably a good idea. Then it all depends on whether a good match can be found, and how torn up things are.
