I don't think you'd even necessarily need to ignore. Roll it out in phases. You aren't going to have to deliver the final finished solution all at once.

Some elements are inevitably going to end up being de-prioritized, and pushed further into the future. Features that do end up having a lot of demand could remain a priority.

I don't think this is even a case of "ask for forgiveness, not permission" (assuming you do intend to actually work on w/e particular demands if they end up actually continuing to demand it), but a natural product of triage.

Why, that sounds positively... Agile. In the genuine original sense.
