I don't think it does hardcode it to true. The API appears to be passing it
correctly. I can see one case of delete_on_termination being set to true,
though thats
for ephemeral or swap volumes.

I think adding delete_on_termination option when attaching a volume to an
existing server
is reasonable. Perhaps add it to the v3 API?
