<p dir="auto">It's only <code class="notranslate">check_changeset_consistency</code> that is used in controllers - the other two methods are used in models so maybe it should be split? Though I'm not sure you could use the same name for both given that controllers can apparently find model validations, which rather surprised me.</p>
<p dir="auto">Then again <code class="notranslate">check_changeset_consistency</code> is only used in one controller so is there any point in splitting it out?</p>
<p dir="auto">This PR looks good anyway.</p>
