Is there a way to make nested loading of code with bundle-configured dependencies work?

Sorry, I don't understand your question. What do you want to be able to do?

From an application, load code which may itself have distinct dependencies described in separate Gemfiles. Plugins are a canonical example - it would be nice to be able to distribute plugins with 'bundle install --deployment' dependencies which can be loaded from the parent application without requiring all possible plugin dependencies to be added to the app Gemfile a priori.

No, unfortunately that's not possible. The ruby interpreter is only able to load a single set of libraries, which is why Bundler has to resolve the entire dependency graph before the interpreter even starts.
