mysqli::rollback() & mysqli::commit() $name param

So...

• mysqli has a savepoint($name) method
  https://www.php.net/manual/en/mysqli.savepoint.php
  which creates a savepoint with specified name (SAVEPOINT `foo`)

• mysqli has a rollback method with optional $name param
  https://www.php.net/manual/en/mysqli.rollback.php
  but the name param is effectively worthless.. rather than create a ROLLBACK TO :foo statement,(as anyone would reasonably expect), instead the method creates a ROLLBACK /foo/` statement (name simply in a comment).. psych!
  is there a @todo in the php code ?
  we have savepoint($name), and rollback(...$name) that doesn't seem to behave as expected

• mysqli has a commit method with optional $name param
  https://www.php.net/manual/en/mysqli.commit.php
  what is the point?
  mysql doesn't have a "commit to name" or "commit since name" functionality
  like mysqli::rollback, this simply adds a comment to the query (COMMIT /*foo*/)

Start with the mysqli::savepoint(), mysqli::rollback(), and mysqli::commit() manual pages linked in the issue, then compare their descriptions with the reported SQL behavior. Check the PHP implementation or existing documentation context to determine what the optional name parameters mean; the documentation is done when their purpose and behavior are accurately explained.
