Yeah, this wouldn't be too hard to do in the client.  I guess I think of
it the same way I think of poor little rarely-used Agena: isn't it
necessarily hard to add Gopher support to a Gemini proxy, but also
what's the point of a dozen different client authors doing the same
thing a dozen different times when it fits so naturally into the proxy
concept?

But, sure, for a tiny in-memory short-lived cache perhaps this argument
is not so strong, certainly less though than for something larger and
longer lived.  I do think that gets tricky, though, it's hard to know
when to invalidate the cache without servers having any way to signal
it.
