The Defiant is a problematic example given we could then say why was Garak on a street corner inside one of the Miranda class ships that got destroyed if one takes recycled footage at face value. I know it's pedantic but the extensive limitations that were placed on them should be taken into account. We know it was intended to be the A but production mistakes happen either models, costumes or dialogue. I mean we ignore the eugenics wars being in the 22nd century and lt jg pips on lt commanders.That's fair. I refer back to the canon NX-74205 then.
Besides that, I think it's great how this new calendar prompts conversations. It feels good to have it back with new content.
If we take absolutely everything as canon verbatim then we end up with quite a mess. Thus contradictions by purists on both Memories Alpha and Beta.
