Library maintainer rules & guidelines

S3.1 Origin is centered on the middle of the symbol

For symmetrical symbols, the symbol must be centered around the origin (0, 0) in the symbol editor.

Exception:

For non-symmetrical symbols, or symbols where this requirement would move pins off the 100mil grid, then the symbol should be placed as close to the origin as possible while observing the pin grid alignment requirements.
