If you were to assert that the move to the CoC has not been handled
all that well, I would have a hard time arguing against you.  On the
other hand, I would also have a hard time arguing that I would have done
any better.

I would like to believe that all the various players have good intentions
as well as the intelligence, persistence, and strength of character
required to have a fighting chance of producing good outcomes.  If that
turns out not to be the case, for example, if hordes of toxic characters
descend on the Linux kernel community leveraging the CoC to disrupt
and to do disservice to its various members, then this community most
certainly has a good and sufficient number of people skilled in the art
of blacklisting email addresses and, if need be, of "git rm".

Nevertheless, to your point about the GNU Kind Communication Guidelines,
given that RMS reportedly said of the CoC "I myself did not like
the punitive spirit of that approach, and decided against it" [1],
significant vigilance and caution might be warranted.  Perhaps deletion
of a certain paragraph from the Linux kernel's version of that CoC has
made the spirit a bit less punitive.

My perception is that these behavioral improvements have been accumulating
steadily since I joined almost twenty years ago.  But if people claim that
adopting the CoC magically made the Linux kernel community way better,
well, that wouldn't be the strangest statement I have heard this year.
A very low bar, to be sure, but a bar that would be cleared.  ;-)
