Storing data in non-canonical form is not "broken." Also, there's more
than one canonical form. The "C" forms compose characters into the
smallest number of code-points possible. The "D" forms decompose them
into fully-general base+combining forms. Programs which disagree on the
form of the I/O will need to translate between the two.

That wouldn't help unless they agree to write the *same* canonical
format. Besides, this is just separating part of the reader's job into
an external program, and in an error-prone way.
