The issue is the output from troff which is later turned into
PostScript.  Or PDF, or whatever, depending on the device troff was
given; default PostScript.  The chapter.set above.

I agree text files on Unix don't need a suffix.

Some programs can act on the pattern to filenames, e.g. make(1).
It can be told how to turn a .tr into a .set and a .set into a .ps.
Even though all three are text files, it's useful to suffix them
descriptively.
