KB-H011 / KB-H022 test doesn't work correctly (false-positives)

Consider this simple test:
https://github.com/paulharris/conan-cci-hooks/tree/test-rm-safe

Even with rm_safe() as per the instructions, I still get errors that look like this:

[HOOK - conan-center.py] post_source(): ERROR: [LIBCXX MANAGEMENT (KB-H011)] Can't detect C++ source files but recipe does not remove 'self.settings.compiler.libcxx' (https://github.com/conan-io/conan-center-index/blob/master/docs/error_knowledge_base.md#KB-H011)
[HOOK - conan-center.py] post_source(): ERROR: [CPPSTD MANAGEMENT (KB-H022)] Can't detect C++ source files but recipe does not remove 'self.settings.compiler.cppstd' (https://github.com/conan-io/conan-center-index/blob/master/docs/error_knowledge_base.md#KB-H022)

Good catch! It will be required for Conan 1.53.0 on CCI.
