When I'm viewing my site in production, I get to take advantage of the extremely useful error pages symfony provides. Unfortunately, this is clobbering my user-facing error pages.

It would be nice if somewhere in the ui of the default app_dev error page, a button was made available to re-render the request using the production error templates.

I'm going to clarify something ahead of time as I brought this up on IRC and some people struggled to understand the usefulness of this: Ideally I wouldn't have to re-enter the same URL in the address bar to view the production template. Reason being that I may not have directly navigated to the page I'm viewing. As a result, things like post variables or anything set server side are not guaranteed to be present.
