I know these project managers. They ask for a 15 line JS helper "library" enterprise level support and they start to scratch their head "what if the developer abandons it".

Only that we're not talking about a 15 lines JS helpers, but about quite big parts that should be in the core and instead they are some 3rd party plugins.

If you're looking for a monolithic solution, Meteor may not be for you. Check out Wakanda and Servoy.

Delegating quasi-core parts of the platform to 3rd party libraries is quite common. For example, the preferred routing package for Angular, ui-router (https://github.com/angular-ui/ui-router) was born four years after the release of Angular, and for DOM state preservation, the ui-router-extras (https://github.com/christopherthielen/ui-router-extras) addon is required.
