Sorry, but I can't find any emails which said this was a bad idea.
If we don't set CONFFILES by default, maybe we need mark a lot of
CONFFILES inside the recipes. I think that mark the CONFFILES under
/etc/ doesn't hurt anything, but help a lot when doing upgrade on
target:

1) When the old file is not changed, it will be replaced by new file.
2) When the old file is changed, it will ask the user what to do (dpkg)
    or save a bak (rpm).
