Sure, that's one. The reason is because spirit numerics are
customizable. And they are even more customizable than the
locales provide. For example, you can tweak the floating point
parsers to handle numbers like:



     1.234567890 exp -200

with the same high performance. And, surely, you can customize
them to handle locales.
