This results in a significant speed-up since we can avoid invoking llvm-cov export on all the object files in target/debug/incremental.

See #1013.

Given that we risk missing something by doing this, I would not recommend it by default in all examples in the README, but just add a note saying that it can improve performance

It doesn't sound like it actually misses coverage if the reported coverage for build scripts is 100% anyway though (at least that was what one report said). But happy to update this to be a note about it improving performance instead if you'd prefer?

From #1015 (comment) it looks like build.rs files were not covered?
