Suggested replacement for use of deprecated VALUES() to access new row values in INSERT ... SELECT ... ON DUPLICATE KEY UPDATE statements

[Jens Hatlak]

As documented here [1], VALUES() used in ON DUPLICATE KEY UPDATE has been deprecated. Neither [1] nor [2] describe the suggested replacement for INSERT ... SELECT ... ON DUPLICATE KEY UPDATE cases. I also checked the 8.0.19 changes [3].

Was it missed?
Please update the documentation to either state
a) what the suggested replacement is (including examples) or
b) that this use case has been deprecated without suggested replacement
