There are many different reasons for a character to have a compatibility decomposition. The oldest Unicode data file, http://www.unicode.org/Public/UCD/latest/ucd/UnicodeData.txt, even contains labels for these. But having looked again through the list of these labels, excluding them seems very appropriate in all cases.
My correspondent said it should be fine to disallow compatibility decomposable characters such as U+328A (CIRCLED IDEOGRAPH MOON) because according to him they would not be used in given or family names.
This would be indeed about as weird as using using circled letters in a Western name. In Unicode, circled moon is followed by circled fire, water,... It's very clear that these are specific 'styles' for the days of the week in Japanese (not in Chinese, don't know about Korean).
