Hi Eric,

As it stands, you've identified a pain point, and you've made a proposal
to  rebase a key part of the architecture on the basis of that pain.

Folks agree with you that it is a pain point, but all of the feedback
you're getting that this isn't worth the schedule slip is, fundamentally,
also feedback on how bad the pain is.  The message I read (and, to be fair,
participated in sending) from this thread is "not bad enough for this".
It's clearly bad enough that Christian, I, and I'm sure others would like
you to create a PR to incorporate what improvements from your proposal can
fit into the current structure.   If that's the conversation you want to
have, I'm happy to jump in.

But I don't think we can ignore the signal that the current state of
affairs actually works and that changing away from it so completely isn't
worth the (new) pain.  I think we will lose both momentum and expertise if
we start over to this extent at this juncture, and I'd rather we did not.
I'm particularly worried that the uncertainty around this could kill the
productivity of the hackathon and London meeting, and that we won't recover
until the next interim, if then.

Not talking about that as we analyze this seems to me to be the wrong
choice.

regards,

Ted
