Just a brief comment on the sentence above.

This is a common thing to hear from coders, and is very rarely rooted in
reality IMHO. Nova does _a lot_ of things. Saying that given an
exhaustive list of features it has, we can implement them in a much
simpler manner is completely disregarding all the complexity of building
software that works within real world constraints.

I agree with this of course - fixing architectural flaws is important
and needs to be an ongoing part of the process, as I mention in my other
mail to the thread. Halting all other development is not the way to do
it though.
