package.json: Why not use "packages/**" to support nested workspaces?

[kynikos]

I haven't been able to find an answer to this, but I can't be the first to have a project with nested workspaces, for example:

packages/
|-example-app/
| |-subpackage/
| | |-package.json (C)
| |-package.json (B)
package.json (A)

package.json (B)

  "workspaces": [
    "subpackage"
  ]

Nx seems to initialise package.json (A) like this:

  "workspaces": [
    "packages/*"
  ]

However in that way npm install will not install the dependencies in package.json (C).

Changing package.json (A) to this solved the problem for me:

  "workspaces": [
    "packages/**"
  ]

Why doesn't Nx initialise package.json (A) to use packages/** from the start? Are there downsides to that?
