No, they don't need to be manually fetched. Optional packages are 
downloaded when they are specified in the dub.selections.json 
file.

What the OP wants is to have dependencies in a configuration be 
downloaded only when the configuration is specified. Currently, 
dependencies are always downloaded unless they are optional, no 
matter where they're listed in the file. And optional 
dependencies are only downloaded when they are specified in 
dub.selections.json.

It would be a nice feature to have.
