I think deinterlacing became popular for three reasons:

- good deinterlacers were too hungry on the CPU to be be used in real-time back then and some new ones are now as well
- some codecs didn't have an interlaced mode (DivX 3.11 for example)
- a lot of times videos were resized to arbitrary sub-SD resolutions.

One method of deinterlacing doesn't throw away any information at all BTW: bobbing.

I agree with you that if your target is DVD on TV then deinterlacing doesn't make much sense. Also remember that a lot of 'deinterlacing' going on now in the AviSynth forum is actually trying to undo bad standard conversions.
