I'll add some additional information:

Arduino IDE 1.x adds a closing */ when Enter is pressed on a line that starts with an unclosed /*:

Arduino IDE 2.x does not have any auto closing of block comments:

The VS Code built-in cpp extension used by Arduino IDE 2.x does allow this to be configured via the autoClosingPairs key in its language-configuration.json file:

It seems this is not configurable via the settings UI: microsoft/vscode#38352

However, that configuration does not result in behavior matching Arduino IDE 1.x:

And that auto-closing behavior seems to be the source of frustration for people who are attempting to comment out blocks of existing code, which is a relatively common use for block comments:
