For interactive functions, it's usually decided by whether the command
can be useful before the package is loaded (i,e,. usually an entry
point to the package).

For functions (i.e. exported from what is basically a library), the same
kind of tradeoff applies:

- is it likely that this one autoload will let other packages use this
  library without a `require` at all (e.g. `define-inline`), or will we
  end up needing N autoloads anyway?
- how commonly is this library used (i.e. is it worth carrying the
  N autoloads in every Emacs session, compared to having to write
  `require` in a handful of files).
