/**
 * Modify list for integration with Bitrix Framework:
 * - removed integration with third-party package builders;
 * - add check variables before using them, see tags: 28122018;
 * - add alternative Promise check for Bitrix Cli, see tags: 02032020;
 * - add export for work in Bitrix CoreJS extensions;
 * - add export BX.Dexie and BX.Dexie3 for backward compatibility;
