在Angular 6应用程序中使用@ angular / cdk 7是否安全？

Question

我目前有一个Angular 6.x应用程序，并且想利用@ angular / cdk 7中实现的拖放功能。我已经将cdk升级到7，并且该应用程序运行正常。

在不将所有Angular软件包升级到7的情况下这样做是否有任何风险？

示例package.json：

"dependencies": {
    "@angular/animations": "6.1.2",
    "@angular/cdk": "7.0.4",
    "@angular/cli": "^6.1.2",
    "@angular/common": "6.1.2",
    "@angular/compiler": "^6.1.2",
    "@angular/compiler-cli": "^6.1.2",
    "@angular/core": "6.1.2",
    "@angular/forms": "6.1.2",
    "@angular/http": "6.1.2",
    "@angular/platform-browser": "6.1.2",
    "@angular/platform-browser-dynamic": "^6.1.2",
    "@angular/router": "6.1.2"
}
