I'm not knowledgeable enough about cars to assume that whatever VW was
doing in the '70s to meet emissions standards would not have been
surpassed by some other technique in the '80s. I was vaguely surprised
to learn that my bay window had a charcoal canister, and figured it was
some kludge.

The received wisdom about them '70s canisters is that the responsible
thing to do was to refresh the activated charcoal. Is that unnecessary?
