Deprecation warnings

[1valdis]

When running npm i -g @feathersjs/cli I see four deprecation warnings:

npm WARN deprecated babel-preset-es2015@6.24.1: 🙌  Thanks for using Babel: we recommend using babel-preset-env now: please read https://babeljs.io/env to update!
npm WARN deprecated nomnom@1.8.1: Package no longer supported. Contact support@npmjs.com for more info.
npm WARN deprecated core-js@2.6.11: core-js@<3 is no longer maintained and not recommended for usage due to the number of issues. Please, upgrade your dependencies to the actual version of core-js@3.
npm WARN deprecated mkdirp@0.5.3: Legacy versions of mkdirp are no longer supported. Please update to mkdirp 1.x. (Note that the API surface has changed to use Promises in 1.x.)

Ideally this shouldn't be the case?

This might take some time to fix because it is pretty deep down the dependency tree but rest assured that all the dependencies in your actually generated application are up to date with no deprecations or security advisories.
