Not the OP but one small thing I do along these lines is compile multiple Elm top-level modules into a single binary with "elm make" and then initialize only the ones I need for a particular page. So instead of one big app, I have lots of little apps that only know a small part of the overall picture.

This also eliminates some of the boilerplate nesting/dispatching you would otherwise need between different Elm models for the price of a very slight increase in the risk of seeing runtime decoding errors.
