Yes, I would have tried that straight away, but unfortunately I do lack the time at the moment. I’ll get back to you @tchr in case of issues.

Also related to the announcement of [SymmetryReduceBZ](https://discourse.julialang.org/t/ann-symmetryreducebz-jl-reduce-the-brillouin-zone-by-symmetry/64603) by @jerjorg I wonder if integrating symmetry reduction was on your roadmap? In DFTK we would love to see a pure-Julian way of handling BZ meshes available …
