As opposed to the high quality buildings being built now?
Well, building regs have come on somewhat in the last 150 years.
Fwiw, I'm not suggesting that it isn't preferable to use period correct materials, I'm just suggesting that it isn't always that practical and may not be the highest priority.
But as I'm wrong on a number of levels, I'll keep quiet now.
It's not period specificity it's the use of materials and repair techniques that function correctly. Cementatious mortars in solid walls do not and will likely cause internal and external damage.
