Mobile app without --mobile-server

I have an existing meteor android app and we have new rest service now.

So I want to change the existing app to use the new REST service.

In future I don’t want to face issues with HCP(Hot code Push) so I want my app completly like offlne app.

So I want to remove --mobile-server flag while building apk so I can push updates using playstore.

Is there any disadvantages or effects with this?

or Is there any other ways to do this?
