That's not the case, it just disables demand caching.

If you want to enable caching for all destinations regardless of
low/intermittent traffic that makes caching pointless, then you
can set:
smtp_connection_cache_destinations = static:all
but there's little reason to do this globally. Perhaps on an inbound
relay that sends everything to a small set of internal servers it is
easier to say "static:all", rather than list the nexthop hosts/domains,
but demand caching is generally sufficient.
