The difference between Office and Invariants is (if I understand the licence
correctly) that Invariant sections can't be large chunks of the manual -
only so-called "secondary sections". It's merely just extending the
unmodifiability from the copyright notice itself to other ephemeral parts of
the documentation, while keeping the meat of the document flexible.
I don't think Invariant sections are a good idea because if one small part
of them is out-of-date (for instance the project website in a section on
"Getting the Software") you can't just update the address. Why someone
would make a section "Getting the Software" invariant is beyond me, but it
would probably fit in the definition of a "Secondary Section", so someone
somewhere would probably mark it as invariant through lack of knowledge. At
least being able to remove an invariant section and replacing it with
something equivalent solves that problem. I still don't like them, though.

Being able to remove an invariant secondary section wholesale allows the
user to build on the meat of the document without having to put all of the
invariant sections into their derived documentation if it doesn't fit (see
"The Reference Card" example for why this is needed).

I didn't read that anywhere (though I may have missed it). Since we're
allowing non-modifyable licence texts (which I think everyone would agree is
a given, and IIRC may be a legal requirement) allowing invariance on other
things which do not affect the "operability" of the documentation/software
doesn't seem like an overly huge problem. Defining "operability" in the
realm of documentation would be the stumbling block.
