Our national housing stock is FULL of places with narrow winding stairs, lead paint, full flow toilets and shower heads, untempered glass, single pane windows, uninsulated walls or ceilings, ungrounded outlets, undersized plumbing, sketchy chimneys, springy floors, etc.

My house from 1890 scored 10 for 10 on your list. I addressed about half of them over the decades, but the other half are just, "It's ok, we'd do it better if we did it over." The additions and any bits "touched" have to meet current code, but the old parts are allowed to be what they are.

I don't feel it detracts from my living experience at all. (I did take care of the "this can kill you" part of the list as well as most of the single pane windows and uninsulated areas.)

A couple of the code mandated changes are definitely negatives, as are a couple of "slightly off" construction problems which required space wasting and slightly dangerous constructs in the house instead of just accepting that the wall at the bottom of the stairs is 2 inches closer than code allows.
