Is there an existing issue that is already proposing this?

Is your feature request related to a problem? Please describe it

RouterModule does not allow to define an array of paths. This prevents me to access the same nested routes by different prefixes.

Describe the solution you'd like

Controllers allow the definition of multiple basePaths like this:
@Controller(['equipment/:assetId', 'assets/:assetId'])

I want to bring the same functionality to the RouteModule such that we can nest controllers like this:
RouterModule.register([ { path: ['equipment/:assetId', 'assets/:assetId'], module: AssetModule, } ]),

Teachability, documentation, adoption, migration strategy

These docs can be updated after the change has been implemented

What is the motivation / use case for changing the behavior?

I want to be able to rename the prefix of nested controllers to better reflect the changed business logic, while still being backwards compatible.
