Indeed, I rather stick to the default options as given in the upstream
release.

Btw., what you can do as well is to set APPDATA in a shell profile,
for instance in /etc/profile.d:

  _sid=$(grep "^$USER:" /etc/passwd | sed -e 's/[^:]*:[^:]*:[^:]*:[^:]*:[^:]*,\(S-1-5-[^:]*\):.*/\1/')
  _prof=$(cat /proc/registry/HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Windows\ NT/CurrentVersion/ProfileList/${_sid}/ProfileImagePath)
  export APPDATA="${_prof}\\AppData\\Roaming"
  unset sid
  unset prof
