It's impossible to cover all aspects of all cases, but obtaining
suitable results is entirely possible.

I'll agree that invariant sections are similar to licenses.
But I'll not agree that they are equivalent.

And we have no problem with maintaining things which are
not the software -- in non-free.

It's true that the license associated with a copyrighted
piece of software must be kept intact when distributing that
piece of software. That's a fundamental requirement of
And where someone puts a political rant into an otherwise free
license, we use it as-is.
But the license serves a very specific role -- in free software,
it is what says that the software is free. And we judge the
licenses based on their content.
Invariant sections do not fill this role. They fill other roles.
And the license requirement that they not be removed is
a restriction on modification.
Modifying the DFSG to explicitly allow invariant sections
should be pretty simple, right? The trick would be making the
modification narrow enough that it won't come back to bite
us in a few years.

Whatever "bogus" means in this context...
...and, nevertheless, this is a reading which is could be legally valid.
This restriction should instead say something like "When distributing
the Document, you may not use technical measures to obstruct or
control the rights of other people to read or further copy the copies
you make or distribute."
