It's not easier than nothing. You don't have to do ANYTHING in mongo. In any reasonable sized web app with a well designed ERD changing is going to result in you stopping coding and doing some ALTER TABLE, DROP INDEX, etc commands before you can start back with the coding.
Also when you want to create a report you can just write a script aggregates the data and fills another collection on the fly without creating the table first. You can even try out 6 different reports at the same time, without issuing separate create table statements.
