Me neither. I think it would rather surprise me if these higher-unicode
digits were considered for the placeholders during the formatting. Since
this construct of {0} and so forth is one for programmers, the input should
only come from Smalltalk code. Since Smalltalk as a language does not
support other numerals than the "basic" digits, I think it is reasonable to
restrict the format method to just consider these digits.

If we decided one day that Squeak should also support Roman numerals or Han
numbers in Smalltalk code, I would reconsider. ;-)
