Yes, I agree. It would have been a good bonus feature - but if it's permanently disabled in hardware, people whining online are not going to make it magically appear...
HOWEVER...

At least the publicly available OMAP35x (similar to but not exactly the same used in N900) technical reference manual lists USB2.0 TESTMODE register. It appears that it could be used to force the controller into a specific mode by software, regardless of the ID-pin or connected devices.

The N900 might not deliver power to the port but other than that I still believe the support might be doable by software hacks.
