Why do you think dependencies are not needed for the help system? At some point they will be needed to resolve cross-references: at install time if you are generating static HTML.

I've not seen any issues that cannot be solved by --install=fake: I have fake installs of a few packages (e.g. ROracle) to allow others to be tested (including their help pages).
