Should balloon-framed houses with open crawlspaces be sealed?

Given a "historical" (ca. 1910) wall assembly, plaster/lath -> framing -> siding (no insulation, sheathing, or vapor barrier), does it still make sense to seal the crawlspace? Is it risky, much like adding insulation w/o also rebuilding the exterior wall to add a rain screen can be?
