Yes, at the same time we'd be excited about more mundane sources from history. The legends about the mighty are interesting, but what do we actually know about every day love from people a thousand years ago? Very little. Most things are speculation based on objects (tools etc.), on structure of buildings and so on. If we go back just few hundred years there is (using European perspective) a somewhat interesting source in court cases from legal conflicts between "average" people, but in older times more or less all written material is on the powerful, be it worldly or religious power, which often describes the rulers in an extra positive way (from their perspective) and their opponents extra weak.

Having more average sources certainly helps and we now aren't good judges on what will be relevant in future. We can only try to keep some of everything.
