IMO the greatest concern with wire-wraps is breaking the wire that emanates from the bottom. The wire is fragile solid core and not very large. Repeated turning and re-positioning of a small board puts stress on those wires.
Also I would not add solder to the wrapped wire. Even if the outside of the wire appears to have some corrosion, the actual metal-to-metal contact areas between wire and post corners were originally gas-tight, so I would assume that without exposure to the atmosphere, those areas are still clean. Large amounts of heat needed to make solder flow in and around that much metal (wire wrap + post) would cause expansion and later contraction that, to my OCD way of thinking at least, might disturb those connections. Why take a chance...
If a wire-wrap joint is suspect, one could always put a meter probe on the wire and another on the post, after scraping away surface oxidation those areas. If there is a problem then unwrap, clean everything thoroughly, do a partial spiral wrap as tight as you can, and apply solder+flux generously.
