That's not true in all applications. Our users deal with terabytes of data but files are typically in the 10-500 MB range. There is however occasional need for a few much larger files. There is also a need for the common files to work with all the other software out there.
In such cases, and if storage requirements aren't too strict, maybe it's a good idea to write a BigTIFF file first. You can next use its size as a very reasonably good estimator of an old TIFF file size. If it's less then 4 gig, you could confidently add the plain old TIFF. Maybe that's not ideal, but in some circumstances it could be a transitory strategy.
Expanding on that idea, maybe in some environments and on some operating systems, it could be a good idea to write a shell extension that can present a virtual old TIFF for every BigTIFF file less then 4 gig in size. The conversion required to be implemented by the shell extension is very feasible.
