That's difficult, because languages and scripture are evolving. Is there 
a difference between Montenegrin and Serbian? Will there be a difference 
for German German and Swiss German (the standardardizations of both 
languages are nearly identical, but there is an important typographical 
difference: ß)

The cedilla/comma below shows the real problem: There is no fixed way of 
writing a letter/sign/glyph (else there wouldn't be different fonts) but 
the unicode model glyph=f(meaning)=F(codepoint) doesn't work that way 
all the times. The relation glyph <-> meaning is more difficult and 
depends on the people.

So setting up different planes for different languages might be helpful, 
but its positive impact won't be so great, I think. But who knows all 
the problems arising from that?
