Thanks, I agree. The general feature is excluding source lines or regions from coverage reports. LCOV markers are one way to mark them; llvm-cov already applies the exclusions across its output formats. I can make that separation clearer in the code and docs. Did you have another marker spelling in mind for this PR?
