I was curious about that "usually". So I had a quick look at my own
.emacs (I use use-package everywhere in it).

You are just about right -- it's about 50% of my cases that a
use-package form contains what is essentially a fix.

My main use for use-package that I think is good are:

- auto-install from ELPA
- using defer to idle loading.
- switching global modes on as well as loading them
- diminishing these global modes
- configuration -- for example, I have global bindings for org-mode
- lots of hooks
- setting load paths for my own packages which are *not* package
  installed


There are some issue here that could do with long term fixes.

For example, diminishing minor modes -- I think we have overloaded the
functionality of minor modes; many (company say, or eldoc) you either
want on or off. Do I really need mode-line space to be taken up telling
me that company is one? And is the mode-line the only place we can
display this information?

Global binding -- key-binding space is precious in Emacs, but perhaps
with tools like hydra, could allow better use of longer bindings.

Lots of hooks -- I regularly hear new users of Emacs complain "well, it
doesn't go X" where X are things like, for example, info on function
arguments or completion. Emacs does do both of these, but you have to
turn them on; perhaps, core Emacs should be more adventurous with its
defaults.

load-path for my own packages: I develop without installing and eval as
I go, but this means I develop source in one way and users get another.
Perhaps, we need better support given some lisp package source, for
rapidly generating a package and installing it, directly in
Emacs-lisp-mode.

Just some thoughts.
