      But if they were only removable without being
    modifiable, then yes, removing them would be the only way to include the
    accompanying documentation while still ensuring that all bits in Debian
    guarantee the freedoms that we require.

Not long ago, people were trying to reassure me that if invariant
sections were removable, nobody would remove them.  I guess not.

This reinforces my conclusion that it is essential for these sections
to be unremovable as well as unmodifiable.
