That wiki says it’s common in hospitals and labs. Interstitial space is not the same as a floor cavity.

Also

The heights of these spaces are generally 6 to 8 feet (1.8 to 2.4 m) and allow easy access for repair or alteration

So yeah not common in a residential building.

    There is no country that only uses Imperial. Americans use grams for weed. And technically what the US uses is called US Customary. Some units are different from Imperial. Funny thing is both Imperial and US Customary are legally defined in metric.
