What are the 'programming language research parts of the ecosystem'?
The only part of the Racket distribution I can see that is specifically 'programming language research' is Redex.
In the language itself there are the metaprogramming capabilities - but all modern languages have metaprogramming.
My experience of the community is it is generally people talking about real problems.
People do use Racket for PL and other research, so a number of PL research papers and conference talks do reference Racket, but it doesn't dominate any of the discussion.
