Having separate commands for outputting the content of a single file and several files would, however, be an orthogonality violation. YMMV whether having a more descriptive name for the most common use of cat would be worth the drawback.

It would fit in the broader methodology of 'single purpose tools that do their job well' or 'small pieces, loosely joined', but yes, probably too annoying to bother with.
