So is the animation/skeletal mesh, and you are looking for micrometer precision on most world applications for skinned mesh usage.
Anything above 1mm precision will cause possible gaps and lines in composite characters, even when properly merged.

Ergo, world origin shifting is the only way to achieve this.
