That's true.  It can be a balancing act.

Most of them are plain bugs, tho (typically fixed by introducing an
autoloaded minor-mode, so the package is activated by enabling the
minor mode rather than by `require`ing the package).

AFAICT this is a missing feature: we obey `help-enable-autoload` in
`describe-function` but we fail to do the same autoloading dance in
`describe-variable`.
