Complexity is entropy. It occurs naturally in all human endeavor. It
takes work to keep things small, orderly, and rational. But there is
also a point where although a tool may be perfect in its conception and
execution, from its own perspective, it is not as useful as a slightly
more disorderly version that does what people want it to do. "Well they
shouldn't want that !" is a common response. Then people write scripts
to do for themselves what the tool doesn't do. Which might be right, but
it might lead to a whole bunch of similar scripts to do the same thing,
just a little differently And that's when we discover that it would have
been better to have it in the one tool in the first place.

So it's a back and forth, trial and error process. Eventually new
balances get struck, and people of like minds and tastes find a new
center, like Plan 9, or other things.

Myself, I do tend to like tools that are smaller and more single-minded
in their function (and that makes it possible to have documentation that
is clearer and more concise), but as an example, sometimes I want the
"-u" switch on diff, to make a patch, sometimes I don't, the default
display is better for a quick review (but I think or expect that the
essential diff engine is being shared). It's all a matter of judgment,
but you can't apply good judgment until you have the experience gained
from trying several alternatives. So things will get bloated up, and
then they will need to be pruned and re-engineered, but hopefully we
don't throw out the most helpful exceptions to the rule just because
they don't fit with some sort of consistency aesthetic.
