Depends. What were the changes? Could be "add headpole/murphy/gaiting" because the horse was sore and running in/out and ended up scratched after warming up. In which case, take notes. His card would list latest equipment as of last start--whether startd or not. It may or may not be announced.
Hardly anyone checks shoes anymore. And most don't report changes. I only report changes if its obvious on equipment check-- and our track MAYBE measures hobbles once a month. And sometimes things get changed after warming up after equipment has already been checked. I've added/removed, hoods, pops, poles, pulled shoes, hobbles in/out all without mentioning it.
