I like your post a lot, I think starting out with racket it would have helped me to get up to speed in understanding that package organization strategy.

The only thing I would like to state explicitly — _because I am unsure that it is conveyed 100% to the reader_ — is that `single-collection vs multi-collection` is orthogonal to `single-package vs multi-package`.

You can use them in any combination you like, e.g. in my [define-attributes](https://github.com/SimonLSchlee/define-attributes) package I use `single-collection` with `multiple-package`. Sometimes packages organized as `-lib/-doc/-test` use `(define collection 'multi)` in their combining package, even when the sub-packages all use a single collection. Starting out that gave me the impression that `multi-collection` was required to use `multi-package` but this is not true.

This is why I prefer it when the combining package uses something that matches the sub-packages, e.g. only uses `multi-collection` if at least one of the sub-packages does too.

I also wonder whether there should be a way to state within the `info.rkt` that this package has no collection / is an empty package that is strictly being used to combine the sub-packages, it feels wrong to specify a collection, when you never want it to contain something (in that particular package).  
Maybe `(define collection 'none)` could indicate that the package has no own collection and is only composed from its sub-packages.
