Not an expert (I just read the docs), but if you only have one binary that you ship, or all your binaries are in the same module, then it looks like a single "replace" directive will do the right thing.

If your binaries are spread across multiple modules, each one would need its own replace directives, so you'd have a bit of duplication. (But maybe this independence is good, since you can upgrade them one at a time?)

If you're publishing a library and don't control the binaries (this is something your customers build) then it looks like "replace" isn't going to work (it's under their control, so they have to do it). If you need to control the exact versions used by your library, you'll want to look into vendoring.
