Checks if a shared newly created variant requires an ABAP package; this is relevant for the VENDOR, PARTNER and CUSTOMER_BASE layers,
whereas variants in the CUSTOMER layer are client-dependent content and can either be transported or stored as local objects ($TMP);
A variant in the CUSTOMER layer that will be transported must not be assigned to a package.

@returns {boolean} Indicates whether a new variant needs an ABAP package
