I tried in IRC and got no response. These messages are copying the

Yes, so do a lot of people. It doesn't.

There is a middle ground: You can not hide it without explaining it.
AFAICT we don't see ~any questions about the reference client waiting
for six confirmations before saying confirmed.

There have been a great many circulated on the network. People don't
report all losses— e.g. we've never seen a report from those who've
burned hundreds of bitcoins in fees on transactions.

I think this is very hard because this matter is rapidly politicized.
There are some in the community who will instantly allege misconduct
when there is a mis-agreement.
Basically: No one sane should want the job, and anyone who wants
should on no account be allowed to have it.
At this point I think we also will get better results communicating
among technical people in order to get the development focus adjusted
in a way that mitigates those risks that can be mitigated and those
cautions that can be offered offered.
After all, if the Electrum project is _unwilling_ to disclose the
limitations of their implementation and security model on their own
site, even after having them pointed out then someone updating
Bitcoin.org to include them will be politically contentious. I want
to make sure that we've followed all reasonable avenues before going
that route— first I attempted informally on IRC, now I've brought the
discussion here... instead of, e.g. starting the process to remove it
from the bitcoin.org clients page.

I agree, thats why I started this thread.
