Keywords typically make for shorter interfaces and function
calls that communicate more, however the shorter interface
advantage and the need to have function calls to communicate
more should be put against the typical downside with this
style, which is very long and complicated functions that do
a lot more than they should, often.

And, because very long functions isn't good style anyway,
those should probably be split up - and if they are split up,
the interfaces will be shorter and the style clear that way
instead, so the need for keywords to do that will also be
reduced or disappear, really.

Indeed, that could be done for every cl-X case where X is
a non-cl-lib Elisp function and cl-X already does everything
X does with the same interface. Those could be cancelled out.

For the cases where there is no such X outside of cl-lib, e.g.
`cl-incf' and `cl-decf' (no "incf" or "decf" anymore?) the
cl-lib prefix could also be dropped. Another example is
`cl-loop'. One could solve this with aliases, possibly.

Because yes, it looks a bit strange that such rudimentary
stuff has to be prefixed to note their belonging to some
particular implementation or library, and even more so when
there isn't any competition or alternative, even?
