Totally agree!
In fact, one of my immediate thoughts when I got one was WTF - no cooling??
Then, I started to see that the oil was used for cooling. In fact in one of the ORNL tests they pointed out how it is really good that oil spray is used to cool the stator windings. At that point, I was just dissappointed that they made no provisions for an external oil cooler. I mean, my Honda Insight uses part of the radiator as an external oil cooler for the CVT transmission.

Regarding adding water cooling, I think it would be tough. The motor casing is very lumpy - its shape accurately replicates whatever is at that place - bearings, bolt holes, the motor stator, etc.

If you have ideas for adding cooling to a lumpy shape - I'd love to hear them.
