They're rarely just jumpers, they're often fuses as well because they have a current rating. 0 Ω are sometimes uses as sacrificial fail safes when there's not a cost budget for thermal self-resetting fuses such as those used in automotive applications. And it's usually cheaper to bridge two pads with a blob of solder than maintain and source another part in the BOM.

I suppose, though, if you look up those ratings, they aren't terribly different from the max current ratings of a copper wire with roughly the same cross-section area.

Well a wire also has a current rating, I guess that's a fuse aswell?

"Fusible link wire" exists - it is sometimes used in automative wiring harnesses (mostly older vehicles I think).
