Converting using IDNA2003 or IDNA2008? :-))

In a data structure designed for computer consumption, why would you not
want to write the computer-readable, as opposed to human-readable,
version of the label? My security spider-sense tells me that allowing
multiple "equivalent" forms of a name in a security context, rather than
requiring a single canonical form, is a good way of getting nasty bugs.
