Regarding naming, there may ofc be other possibilities. I considered spelling the level out but discarded that option due to its verbosity. I find this quite elegant actually. One might argue that it's not general enough, with 2 to 5 hard-coded. But thinking of the use-case a bit more, I struggled to find a reason for more dynamics.

I don't object to the mailing list RFC method of doing things, but in this case it felt like a too small contribution for that trouble. Had there been a more streamlined pull-request workflow than the list I'm sure I'd have taken another decision. In this case the option was to just not do it due to time and energy constraints.

thanks -- in the future, I suggest discussing such additions on this
list before committing them. In this case, I think we could come up
with better option names than "show2levels", even if I don't have a
better suggestion right now.

Mandatory nitpick: the log should contain proper sentences, ending
with a dot. I'm mentioning this because your other commit has the
same small error.

It sure is, thanks for taking care of this,
