What affect does this have on user timings in GA?

I modified this so that it always logs ga() by default. It will only stop logging once analytics.js is loaded. This enabled me to reduce the conditional statement and change the logic of the filter.

  <?php if (apply_filters('soil/loadGA', $loadGA)) : ?>
    <script src="https://www.google-analytics.com/analytics.js" async defer></script>
  <?php endif; ?>

Looks a lot cleaner now, in my opinion. I also decided to throw in s,o,i,l just for kicks.
