It’s odd that they didn’t include Nim in the benchmarks in their paper: https://dl.acm.org/doi/pdf/10.1145/3360551
Nim can be sold as a "A strongly-typed and statically-compiled high-performance Pythonic language" as Seq (although it is more than that and does not actually have as a goal to be Pythonic, see https://nim-lang.org/ or https://github.com/Araq/nimconf2021/blob/main/zennim.rst).
Still, given the small size of Nim community and even smaller size of the genomics nim subcommunity, I would say it is not that odd that is not included in the benchmark. The existing nim genomics library might not even cover the functionalities required by the benchmark.
Seq claims that vast majority of python programs would work as is. I have not validated that claim, but Nim can absolutely not make that claim. Any python library would require substantial porting effort to be translated to nim.
Of course Nim is statically typed, but a lot of Python code that does not use dynamic typing heavily can be ported to Python surprisingly easily.
