Maybe you are right (and I am no expert in this), but quite a few documents use list-table for sysfs status: https://www.kernel.org/doc/Documentation/admin-guide/hw-vuln/mds.rst https://www.kernel.org/doc/Documentation/admin-guide/hw-vuln/spectre.rst https://www.kernel.org/doc/Documentation/admin-guide/hw-vuln/tsx_async_abort.rst
