software != documentation, you cannot compare it like you do.
Documentation in the formats debian can distribute is a subset of software. Software != programs, remember (see emails about dictionaries, origins of DFSG and anything else you want to clarify that).
And my example was just that, an example for why I believe invariant sections can be useful.
I cannot tell what "that" refers to, sorry. My example was why your argument holds for programs too. Doesn't mean I agree with it.
