That's correct. Section 7 authorizes 'additional permissions'
generally and a limited set of "non-permissive" additional
terms. Conceptually 7a through 7f were seen as categories of
'non-permissive' terms over and above the conditions of GPLv3 that do
not violate the general rule against 'further restrictions'. These
were designed to codify aspects of FSF interpretation of GPLv2
including license compatibility doctrine as well as extend it in some
ways (e.g. 7f is intended to provide a basis for Apache License 2.0
compatibility with GPLv3 by abstracting from the condition of Apache
License 2.0 section 9).
