This is how we went with https://wasp-lang.dev/ (a DSL for building full-stack web apps). It is a very declarative language (config pretty much) and there is still plenty of work around tooling, but also enabled to cut down on a lot of boilerplate.

Another route to consider when implementing a DSL, is to make an embedded one (e.g. like Terraform or Pulumi have, even both at the same time). That doesn't resolve all the tooling problems since there is still a compile step, but might provide a more integrated experience, although at the cost of brevity.
