I see the invariance of licences as a practical consequence of copyright
law.  If a licensor (note: not author) says we cannot modify the licence,
that's a no-op for packages under that licence: we should be giving our
downstream recipients the copyright licence as we got it anyway.

If you put a licence as an uneditable part of another work (putting a
GPL copy into a FDL invariant section, for example), then it is a bug.

I don't understand this question. The licence is granted by upstream.
We may or may not be able to release a derived work under a different
licence, but as long as we can release it as free software under the
same licence, that meets the DFSG (IIRC).

Hope that explains,
