This is a bit of a stretch goal at the moment, but long-term we should switch over from using ASE's DFTB+ calculator to the DFTB+ ASE calculator developed by the DFTB+ team here. Since it's new, there are likely bugs that need to be sorted out. The benefit is that it's maintained by the DFTB+ team and has a cleaner input syntax that is less prone to silly typos.
