It's really more "by physics." You can pick how you want to run a tungsten filament and end up with either a long life bulb, or a high(er) efficiency bulb, but not both. The ~1000 hour goal was, at the time, an attempt to optimize the total cost of lighting - bulb and power combined. As your bulb lasts longer, you get rather fewer lumens per watt.
A typical 1000 hour rated 60W incandescent (an old one, not the new halogen "efficient" ones - 28% less power for 28% less light) will put out around 850 lumens. I have a 20k hour rated bulb with the same output - but it pulls 75W. Over the lifetime of the bulb, that increased power use is quite a bit more expensive than replacing bulbs would be - but they're designed for places that are harder to access, or that are high vibration (typically, long life incandescents also have more supports, so they work better in higher vibration environments).
There's no magical tungsten filament, 60W, 850 lumen bulb that will last 10k+ hours. It's simply not possible within the normal constraints.

This new tech, though... I'm very excited by it!
