Can we please just use a space for thousands and something else for decimals? Use a comma, point, hedgehog emoji ๐ฆ or whatever happens to be traditional in your country, but please make sure it will never ever be confused with a thousands separator.
We solved it in Hungary by absolutely not having a thousands separator. At least not officially. A couple of people and systems use space, but most of the people doesn't separate thousands at all. The decimal separator is a dot.
