It's historical.  Older versions of GPG generated keys with a standard
hash preference of RIPEMD/160 before SHA-1.  When GPG later started
using that hash preference to decide which hash to pick, this resulted
in people who were expecting SHA-1 to suddenly get RIPEMD/160.  To
restore the old behavior, we stuck a SHA-1 preference in
personal-digest-preferences.
