To me, classic rock is a subgenre of its own. It's a certain style of rock not just how old it is. The Clash are from the 70s but aren't considered classic rock, they're punk. Obviously a lot of bands can fit into different subgenres but to me, Nirvana and other grunge bands should not be considered classic rock.
However, I don't intend to muddy the waters but it bears mentioning, within the genre that is called "Classic" you'll find Rock, Southern Rock, Progressive and early metal.
Not to mention that the genres blur back then too. Rush, active since 68 just released a new album a few months ago are certainly "classic" and prog, but early Rush is as heavy as Sabbath.
Zeppelin, credited as one of the first early metal bands are certainly classic, but also have a prog vibe too.
I think then "classic" isn't really a genre, but an age modifier for certain subgenres.
I can also say this, this is a conversation I wish we could have over beers at a rock music bar while listening to this same music.
