Identical icons are not necessary, these (identical) default icons would
only be supplied for those files that don't already have on icon of their
own. It might be madness that Delete, Copy, Date, etc. all have the same
icons, but that is better than them having NO icons (which is the case
now).
If a logical-space object has no icon, the user can attach to it only
through the CLI. The distance of "DELETE" from "COPY" in keyboard space is
1 + 116 + 11 + 113 = 241 keyboard units _minimum_ with the extra two
keystrokes for the "T" and "E" in the blunder possibly adding another two
thousand units.
It is far better that the Delete and Copy programs be kept far apart by
restricting access to CLI than to provide identical default icons, which
represents the worst, the nadir, the
exactly-what-you-do-not-want-under-any-circumstances case.
Default Icons _must_ batter the user with the Campbell's Soup Aisle at the
Hypermarket effect. Warhol unleashed such imagery in the sixties and sent
an entire generation of intellectuals rushing to mind-numbing
pharmaceuticals.
