It being in the dump isn't really "enough" - in a real hex editor, you
can make changes on the ASCII side and expect them to be reflected in
the hex side (and ultimately the binary file), whereas using xxd [etc]
means the ASCII side is static and is ignored when read back in.

This does have its place, though... It's basically an editor-portable
version of the recipe that vim provides for using xxd to "edit" binary
files. Which is itself a compelling enough use case for xxd to be
included with vim in the first place (as far as I know xxd has no other
vim-related purpose). But it's not a hex editor.
