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

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.

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.)
