I think that is exactly what we'd would have todo. We exist as a project
to serve the needs of our users and it seems pretty clear from the survey
results that users are deploying the EC2 impl in significant numbers,
so to just remove it would essentially be ignoring what our users want
from the project. If we're saying it is reasonable to ignore what our
users want, then this project is frankly doomed.

If the external EC2 support doesn't work out for whatever reason, then
I don't think the fate of the in-tree support is at all clear. I think
it would have a very strong case for continuing to exist.
