I don't see how they could be obsoleted. What we know of Rome is very often through late-Roman scholars. We'll need these texts to disprove modern anti-historians, who make claims about our origins to drive reactionary politics. A Roman example--as described in Mary Beard's "SPQR"--is how imperialists claimed Rome was always ruled by kings, attempting to erase its Republican history. Contemporary populations accepted that viewpoint because they didn't have access to history. They're still relevant. Frankly, I am grateful for even your cursory summaries.
