From the docs it seems like proxy_cache_valid must get a number, can
it get something to tell it to store indefinitely (until purged or
until LRU)?
Something like:
proxy_cache_valid infinite;

Currently there is no way to say infinite, but you can set

 proxy_cache  /path/to/cache inactive=2y  ...;
 proxy_cache_valid  2y;
