Pulp

One can specify a pip_version_specifier to point to a specific plugin release. There is also a pulpcore_pip_version_specifier which points to a specific pulpcore release.

On the master branch it makes sense to unset those and have them set only for releases.

Their behaviour is inconsistent when they are unset and might lead to a broken config. To use the latest PyPI release, one can set pulpcore_pip_version_specifier to 'null'. To use the latest PyPI release for plugins, one must remove it from the config, because setting it to 'null' will generate a broken config, it adds 'None' to the plugin name.
