What sort of classes do you mean? Views? Models? Other? For us it hasn't changed much. Our apps were pretty self-contained so that splitting them into separate services isn't very arduous.
Stuff that is shared between apps is often related to 3rd party integrations, which could be moved into a separate (often asynchronous) worker/ service. In reality most of these design choices are done on a case by case basis, based on time/ cost/ maintenance.
