Action button classes inconsitent

Having created a sample Course as part of early testing, I see that the Finish course action button is neatly style using the Bootstrap staples, btn, btn-primary, and btn-small - all good.

No so for the Revisit action button though...

I like to promote the idea that all actions button be styled with the btn flavoured classes and that, in the case of the Revisit button...

<div class="lms-start-link">
<a href="/course/6/start" class="start-link start-link--revisit" aria-label="Revisit Example LMS Course">Revisit</a>
</div>

...the additional start-link start-link--revisit classes be added instead to the wrapping <div> rather than the anchor itself.
