Why not additionally create a metapackage from the moreutils source that depends on the collection of other tools that seem worthy?
Then the tools built by moreutils itself would go into moreutils-base, and the moreutils package would depend on moreutils-base and (depend or recommend or suggest) on bogosort, renamutls, etc.
When I started using Linux, I discovered most of the main tools by browsing the info page for coreutils. So I think that having one big package with all missing tools and proper documentation is the way to go.
