It may be useful to add tests using a testing library like Jest to add some unit test. While tests may ensure that the code keeps working, it's also useful for new developers to see how to use the library by using the existing unit tests as examples of whats possible.

To be able to use the package it would be useful that its actually published on npm.

I can imagine a lot of useful use cases where I care about having a rewrite engine, but not a whole lot about a specific DSL. Let's for example say that I want to implement a new computer aided algebra system, or an optimisation in a compiler stage; in those cases I'd like to reuse an existing rewrite engine so that I don't have to reinvent the wheel, but I don't want to write a new DSL since it should work with the product I'm writing (like a CAS or a compiler).

The DSL is mostly useful for people who want to use the tool as a standalone tool and not as a library in their own application. If every JavaScript library implemented their own DSL with a custom parser then you would no longer be writing JavaScript but instead a bunch of different DSL's.

This is my biggest gripe with rewrite systems like Maude, you spend more time learning the specific language than actually using it for anything productive, and its non-obvious how to actually integrate it in a product and not just as a toy.
