I did consider it, but thought it was better not to since this is not
a security issue -- but I see it's actually listed in MAINTAINERS (in an
entry I'm changing, no less... *facepalm*)

Added to Cc, beginning of the thread is here:
https://lore.kernel.org/all/20230305220010.20895-1-vegard.nossum@oracle.com/

I find this a strange sentiment. All the major Linux distros have a
presence on the distros list and it remains a valuable resource for
coordination.

I think most of the friction of the past should have been resolved by
the distros list actually updating its rules last year (if not 100%
according to your wishes, at least a good step in that direction), any
remaining problems should hopefully be resolved by improving the
documentation so that issues are not sent to the distros list prematurely.

Is the elephant in the room that Android vendors are not rolling out
kernel updates in the 7-14 days given by distros to publicly disclose
the reported issues? If so, then I think this is the real issue here,
and it should be stated outright.

I personally think it would be a mistake not to include the info about
the other lists, both because I think they have real value (and I do
think they represent Linux kernel users, if not kernel developers) but
also because, as Willy said, people will find the wrong information
elsewhere and submit issues anyway, people are still going to want to
request CVEs (regardless of what you or I think about them), etc.

Anyway, I don't represent s@k.o so I don't decide, I really just want
security for end users and as responsible disclosure as we can hope for.
The patches are out there so feel free to use whatever you want from them.

Thanks for looking it over.
