I understand that we have different preferences and those often depend on how we use the keyword fields. To me the idea of name reversal in a keyword field doesn't make a great deal of sense because the field is primarily for the purpose of searching, unlike a database where you might want a table to list surnames first.
Still it's no big deal for me as I will do most of my keywording in LR or Acdsee which thanks to Exiftools can be made to work together.
