Our menus are mostly made for _users_.
The more common are users accidentially enabling CONFIG_BROKEN and then
wondering why a driver isn't compiling or working.
And in my experience, when searching whether hardware might be supported
a grep through the kernel sources brings you more than reading often
outdated Kconfig help texts. Besides this, a BROKEN driver usually has
the same value for the user as a non-existing driver.

In reality, people accidentially turn on CONFIG_BROKEN, enable a broken
driver, and wonder why it isn't working as expected.
If you know the driver is marked as BROKEN and if you want to use it
despite this, editing the Kconfig file is trivial.
Unless you _really_ know what you are doing, no driver for your hard
disk is better than a broken driver.

Enabling MAGIC_SYSRQ for being able to sync the disks for crashed
machines...
