Looking at what it spits out, I find > myself wondering what good it is. As one use case, it's important for scripted regression testing. Running diffs on PostScript output is often not very illuminating, but running it on -a output easily enables you to home in on exactly what the typeset difference is between one run and another. It also has one very valuable output property: outputting the string "<hy>" to represent hyphens that groff has inserted for word breaks, while outputting all other hyphens as hyphens, makes it easy to grep for (or highlight in "less") word breaks while ignoring all other hyphens, even ones that otherwise appear at the end of a line. I don't know of any other output format that has this property. (Yes, groff lets you change the hyphenation character, but for real-world output this is almost never done, and it's absurd to have to alter the document just to check something about its output. This is exactly what an output switch is for.) Please do not remove the -a option.
