I've found solution, approved by Magento team. Because if you use approaches with block rewrites or plugins and you have some extensions that use Breadcrumbs block or Magento\Catalog\Controller\Product\View.php, you'll have problems.
So, you have to customize just app/code/Magento/Catalog/view/frontend/web/js/product/breadcrumbs.js.
So, here are full code:
/**

* See COPYING.txt for license details.
*/
define([
'jquery',
'Magento_Theme/js/model/breadcrumb-list'
], function ($, breadcrumbList) {
'use strict';
return function (widget) {
$.widget('mage.breadcrumbs', widget, {
options: {
categoryUrlSuffix: '',
useCategoryPathInUrl: false,
product: '',
menuContainer: '[data-action="navigation"] > ul'
},
/** @inheritdoc */
_render: function () {
this._appendCatalogCrumbs();
this._super();
},
/**
* Append category and product crumbs.
*
* @private
*/
_appendCatalogCrumbs: function () {
var categoryCrumbs = this._resolveCategoryCrumbs();
categoryCrumbs.forEach(function (crumbInfo) {
breadcrumbList.push(crumbInfo);
});
if (this.options.product) {
breadcrumbList.push(this._getProductCrumb());
}
},
/**

_resolveCategoryCrumbs: function () {
var menuItem = this._resolveCategoryMenuItem(),
categoryCrumbs = [];
if (menuItem !== null && menuItem.length) {
categoryCrumbs.unshift(this._getCategoryCrumb(menuItem));
while ((menuItem = this._getParentMenuItem(menuItem)) !== null) {
categoryCrumbs.unshift(this._getCategoryCrumb(menuItem));
}
}
return categoryCrumbs;
},
/**

'title': ''
};
},
/**

*

_getParentMenuItem: function (menuItem) {
var classes,

parentMenuItem = null;
if (!menuItem) {
