LGTM
I suggest you add to every Debug() message whether its client or server. If you are running standalone node code, you know, but almost all the code I debugged had both a client and server in the same process (all our unit tests do), so having intermixed debug output and not knowing whether it was from client or server state made the debug output not very useful. I added client/server indications to both js debug statements, and the C++ fprintfs I was using.
Would be useful to add some info on how to enable the debug messages. I could't figure it out in 2 minutes of grepping and tag searching. I'm sure its only a couple more minutes till I find out how its enabled, probably I can git blame and find the original PRs, but a few comments in debug_utils.[h,cc] about how its supposed to use would be very much appreciated.

I think "Not yet ready for " would be more clear than "Bailing out". The debug is mostly useful while reading the source, but Bailing sounds to me like a permanent state, but its just temporary.

I replaced all occurrences of Bailing out of with Returning from, that seems like the most accurate statement
Done 👍

Doesn't land cleanly on v11.x-staging. Does it depend on #26951 ? |
|
I'll try to cherry-pick it onto #26951 and see if it land clean there. |

yeah, cherry picks clean after TLS1.3 |

This is an attempt to make investigating the TLS state machine a bit more feasible.
