In my experience, this decision is correct. Noscript does cause the browser to bog down and do all manner of annoying things that causes instability.

As a project lead, you get to decide things like what goes in the project or leaves. Not everything needs a discussion once it has been decided.

I suspect the "not allowed to be discussed" is implemented so that these discussions are bypassed and those that don't like the decision can simply vote with their feet.
