 - `prefer-skip-optional-pointer`: a global default that you do _not_ want the "optional pointer" generated. Optional fields will not have an "optional pointer", and will have an `omitempty` JSON tag
-- `prefer-skip-optional-pointer-with-omitzero`: when used in conjunction with `prefer-skip-optional-pointer-with-omitzero`, any optional fields are generated with an `omitzero` JSON tag. **Requires Go 1.24+**
