Test markers can be used to easily (de-)select tests, and colcon exposes mechanisms to do so. Linters are a category of tests that are commonly called out.
Additionally, if we move the imports for some of our single-purpose tests into the test function, we can avoid installing the linter dependencies entirely. This is a common case in platform packaging, where linter errors are not actionable and the dependencies are not typically installed.
When this change is merged here, I'll make the same change in the extension template package and eventually other colcon packages.
