RAW format is all the information captured by the camera's sensor in
an unaltered state(though sometimes lossless compression is used,
depends on the camera). To generate a TIFF that sensor data has to be
altered and when you do so information is lost.

Part of the reason we have not yet started to convert to DNG, I love
the format but you are right all the eggs in one basket. of course
we're still tied to the camera maker's format by not converting to
DNG... What I'd love to see is something like DNG but totally
open for any company to use, I feel it is leaning that way, but
slowly. Hassleblad digital backs support DNG and Sinar is working in
that direction as well... or so they say. Leaf(now owned by Kodak)
works with adobe to keep their digital back compatible with CameraRAW
But yeah, this is a problem and a fairly big one...
