When using ContentService::createContentMethod, new locations are persisted using eZ\Publish\Core\Persistence\Legacy\Content\Location\Gateway\EzcDatabase::createNodeAssignment() where the priority is not stored. As a result, the LocationCreateStruct::priority property can not be used with legacy storage engine.

Could we fix this by adding a new SQL field in the eznode_assignment table and using it in eZ\Publish\Core\Persistence\Legacy\Content\Location\Gateway\EzcDatabase ?
