This all sounds very reasonable, except that it's not actually all that
reasonable at all.

We have to divide our time between exploring, implementing, and
communicating. The demand for communication is infinite, as you've so
ably demonstrated; if we provided all the communication that was
demanded, there'd be no time left for doing, and we'd all lose. So, I'm
sorry if my explanation seems inadequate to you. Perhaps you could look
at it as half full rather than half empty: you got quite a bit of
attention, you got your idea heard, you got confirmation that these
ideas had been seriously examined before, and you got some explanation
-- all at the time basically of your choosing. That's a lot; sorry if
its not enough for you.

The bar for "idea should be on the table" is not "Gavin thinks it is
good enough." For that matter, I'm not even sure what it means to be
"on the table" (or whether this idea is, or isn't on the table, or even
where the table is.) But we've discussed it and considered it to no
small degree, and will probably consider it some more. I think that's
all the table-hood you can reasonable ask for.

We've shared some of our thoughts. Hopefully, enough to convince you
and others that this is not just something that never occurred to us,
but that it's been examined and some smart people have some serious
concerns. If that's not enough for you, I'm sorry. We try very hard to
balance the various responsibilities of "doing" vs "communicating". I
understand that we can't make everyone happy.
