For now we are modifying locale-archive, but we are aware the this causes problems with container overlays, and are looking for a solution where this works on a per-file basis with each new subpackage langauge contributing a new loadable optimized binary locale file. The stepping stone will likely be: _install_langs (to limit languages) -> subpackages that modify locale-archive -> subpackages that install their own files Please remember the core runtimes are key part of the OS, and we make these transitions slowly and gather metrics about how effective each step was and how many bugs we got, and if the intermediate changes broke anything. In the end we may just skip the intermediate step depending on testing, but I won't guarantee that.
