David and I just looked through this.  It looks pretty good.
Here are some comments:

- In the first patch "return true" is indented incorrectly

- In the documentation patch please move mention of this variable down
  to the bottom.  It is not important information for general authors
  learning the command.  Certainly this information does not belong
  in the short usage summary section above the full command signature.

- The related-cache-entry warning is unnecessary overhead and does quite
  a bit of work for a command that is supposed to do nothing.  The stated
  use case of this feature is for packagers to add -DDISABLE_... arguments
  to scripted calls to the "cmake" command line.  If they are adding extra
  unused arguments defining things related to a disabled package then the
  generic cli warning infrastructure will already complain about them.

Thanks,
