mongo-db-collections is getting this information from
.system.namespaces which has been deprecated since MongoDB
3.0

Which ones?

It works, but anything that MongoDB has broken backwards compatibility
with in the API won't work. I did a brief perusal of the docs and it
doesn't appear that any essential features are broken. It seems like
they just changed how some reflection happens.

Yup

The documentation is here: https://docs.racket-lang.org/mongodb/index.html

I expect you will mainly care about the basic operations --
https://docs.racket-lang.org/mongodb/Basic_Operations.html -- what is
something you wish it contained? It is extensive and documents
everything that is supported. (Although, of course, you have to decide
how you want to use it.)

I was hunting for a no schema solution. I've used MongoDB in the past
with great success and saw it for DrRacket. I'll look into using the
redis package. At my stage of racket experience, I'm not ready to
delve into the source code of MongoDB without spending lots of
time.

Are you looking for no schema or no ACID? If the latter, the git version 
of the db library now has experimental support for Apache Cassandra.
