I encourage you to do so. I'd argue that displaying the Unicode 
discretionary hyphens mid-line is not Unicode-compliant. Manual 
hyphenation is often necessary in some languages when you deal with 
personal or location names, or if a hyphenation dictionary for a certain 
language is simply not available. Therefore occasional discretionary 
hyphens may very well exist in source texts.
