It's a fine lens, and pairs well with the S5; but a big point of a rangefinder body is compact, and while the 20-60 is fairly compact for an L-mount zoom with that range, it's still fairly large in an absolute sense. At least compared to what I normally work with, film era primes and wide-to-midrange zooms. I can take some comparison shots tomorrow if you like; but it's probably at least 30-40% larger than, say, a film era Minolta 24-50 or 35-70, which filled much the same role.The Lumix S 20-60mm not small enough for you? It's a brilliant little lens, not at all big & heavy for the focal range.
More to the point, it balances poorly on my Sigma fp, which I'd guess is in at least the same ballpark as that hypothetical rangefinder Lumix L-mount.
Panasonic's kit zoom in the early M4/3 days was the 14-42, which wasn't bad. But it didn't really go well with their first rangefinder bodies, the GF1 and GX1; by the time they got to the ultra-small GM bodies, they designed a new lens to match them, the 12-32. And then they shipped that lens with all of the rangefinder-style bodies after that, IIRC - because it was a much better fit. So if they do a rangefinder L-mount, I'd like them to do something similar, and make a lens that better matches a smaller rangefinder body.
