Looks good to me. I do not see anything obvious that is bad, apart from the few nitpicks outlined above |

the "serial console" over USB would be garbled badly after switching to "platform = espressif32@6.7.0". this did not happen to the upstream version of MessageOutput. we used Serial.flush(), which seemed to be good in the respective context. however, the changes in github.com/espressif/arduino-esp32/pull/9462 made flush() detrimental. we remove the use of flush(), as it seems not to be required (in particular, the upstream project does not use it).
