Do you mean for input, or for output?
For output, there's no problem with that; see my second patch, here:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=684128#88
If the {Ki,Mi,Gi,Ti}B units were to be used for input, then the
installer text would have to explain that. However, it was stated that
it is not now feasible to get new text translated. This is why I wrote
the patch such that binary or decimal units would be selected
automatically, possibly depending on a boot parameter; no text changes
are necessary.
In any case, not everybody agrees that the "correct" units are those
officially certified for the convenience of the hard disk manufacturers,
rather than what has been conventional usage for decades. I offer again
the example of lvcreate(8), which only provides the binary units, with
"incorrect" symbols, and does not see any need to even explain this.
