Doom 3 BFG is probably to counteract piracy.
The XBLA versions are placed in the DVD as GOD packages, their easy to copy and if they where copied to the HDD then they could also be copied to USB drives and be redistributed to others which don't have the game.
Atleast that's my theory behind.
I haven't seen the disc structure of Doom tho.
As for Halo 3.
The few seconds that it loads the map hardly makes a difference.
I'd rather wait a second or to lower on one or 2 days then having to deal with annoying DVD noises + extra wear and tear on an already delicate piece of hardware.
Fan noise can be slightly blocked out tho.
Cutting away the metal fanmesh on the back of the chassis does eliminate some noise but most of the noise comes from the plastic fanduct.
If you'd remove that then the console would be nice and silent actually.
But yeah that would involve soldering a fan on the Mobo to move air away from the heatsinks as the back fans don't draw heat away as much anymore.
As for reliability.
That's a matter of keeping it clean and also user responsibility.
If you keep the console in a well vented area and pretty dust free then it'll last far longer.
RRoD is not inevitable but it can be post poned.
Friend of mine still plays with a launchday Xenon (hours on end) and it never even 2RL'd
