Well, I have no horse in this race. But the reason it's like this for
Russian is that Oleg, Teodor, and crew set it up that way ages ago.
I'd tend to defer to their opinion about what's the most usable
configuration for Russian. You could certainly argue that the situation
is different for $other-language ... but without some hard evidence for
that position, making these cases all behave similarly seems like a
reasonable approach.
