extensions as legit TIFF. Bob's 3 bits per pixel palette images are a perfect example. Nowhere in the spec mentioned this is. But it is a logical extension of what is mentioned, and it is completely unambigious.

There is every indication that 3 bits per pixel palette images will become the wave of the future. Bits are saved.

The really annoying "new rule" that seems to have popped up recently is that 24 bits-per-sample images are supposed to be swapped for endianness. To me that is still a resounding "huh"? I have yet to encounter a CPU with a 24-bit processor word.

It doesn't require a certain word size.

Windows prefers everything as BGR, while other OSes prefer RGB. Anything that is a multiple of 8 bits is subject to byte order rules (I have yet to see a 96 bit word CPU, either - but extended precision floating point is also subject to byte order).
