The answer is definitely without question sometimes. It's been a while since I looked at the code in mailman and sympa but my recollection is that they usually combine mail to the same domain, or maybe same MX, into a single multi-recipient transaction. Except sometimes they split them out with VERP bounce addresses to see what is bouncing. There are parameters to adjust how often they send separate copies. Commercial list providers like groups.io invariably send separate copies to each recipient with a customized link at the bottom for subscription management. The important multi-recipient use case is the one Ross is describing, enterprise mail systems where everyone cc's each other.
