Well, the old hash, called QuickHash, is a simple home-brewn hash
that doesn't really have a perfect distribution as you guessed,
but it is fast - doesn't use too much CPU.

As CPUs are a lot faster today, the diablo developers decided to
switch to a real hashing function, so now it is based on MD5
if I'm not mistaken.

However the release version of Diablo is still 5.0, with only
the old quickhash. The new hashing function is part of 5.1 which
today only exists as an alpha CVS snapshot. It has been like
this for years, diablo development has mostly stopped alas.
Still a lot of people run 5.1 snapshots (I do).

So for compatibility reasons it would be a good idea to support
both. The added code complexity is minimal.
