It's not a good assumption that the client environment will match the
server environment.

This seems more reasonable. Previously we discussed how to send
usernames and passwords to the database because the encoding they are
sent in must match the encoding of the database these values were set in
(which may be different than the database you're connecting to). At the
time we decided that a connection option to configure this wasn't the
right idea and now always send these values as UTF-8. I don't recall
why we made that decision, but checking the archives might provide some
additional information on this case.
