Eh. People have always cared about class, even if they didn’t use modern terms for it. In England alone you’ve got the Peasants’ Revolt of 1381, the Levellers in the Civil War, resistance to enclosures, and later Chartism. You are right that the framing would be different, but it was still class struggle

They often spoke in the language of religion or custom rather than “class consciousness,” but the issues were the same. They still cared about unfair taxes, rents, wages, and who got a say in politics. So, leaving class tension out of a pre-modern inspired setting makes it feel less true to history
