It would be better to pass formatted decimal string to translator method than mixining into vanilla. It has an advantage of utilizing DecimalFormat for more detailed configuration.

Maybe, but my mixin is also working and I can just use StatCollector.translateToLocalFormatted or String.format with number formatting from lang file for a simple text.

Hmm, I don't like it, but it won't harm other mods, so it's fine I guess
