This is to reduce the size of the bundle users have to install.

Description

In 9.0.0 we introduced a change which depended on lodash as a whole, which meant our bundle size increased. We need to ensure our bundle size is small enough so customers can depend on it at the edge for serverless functions.

Unfortunately this is bad for security as these packages are very old and some of these packages have open CVEs which are never going to be fixed. I haven't verified if these packages in particular have open CVEs, but every package depending on lodash.pick got a vulnerability a few days ago. Additionally, if there's ever a lodash v5, these packages will not be updated. https://lodash.com/per-method-packages

As that website explains, you should be able to use the main package and import e.g. lodash/includes.

You can also use lodash-es and get tree shaking if your build pipeline supports ESM. https://www.npmjs.com/package/lodash-es
