I've spent some time looking at Racket open source projects, and I did not come away with the impression that one must start by creating one's own #lang. There are a lot of custom DSLs out there, but it seems to me that most of them come about, not because using Racket compelled the author to create a DSL, but because creating a DSL compelled the author to use Racket. No other platform I know of (not even MPS) seems to even come close in terms of ease of use and number of batteries included.

I could admittedly be projecting here. Wanting to create a DSL is what brought me back to Racket after a long hiatus. But I don't think so. Exhibit B is that, if you go to Racket's Discord or Slack, you'll see that people are mostly discussing how to solve concrete problems with standard language features. The volume of talk about macros and #langs is much, much smaller.
