Does the new db_hotcopy utility inhibit database checkpoints, so that
no log files which still have to be archived are removed in the
DB_LOG_AUTOREMOVE case?

db_hotbackup is a utility separate from your application and so it
cannot modify it to stop checkpoints. DB_LOG_AUTOREMOVE is
incompatible with doing hot backups.

Ah, okay.

In theory, a lock could be acquired which would prevent log removal
while a hot backup is performed. I just wasn't sure if Berkeley DB is
doing this.
