You don't really want company wide consensus on every point in the RFC. That should be reserved between the author(s) and their immediate teams. Setting/allowing the expectation that any comment made will be reviewed and responded to until everyone is in agreement about it is going to make things miserable for everyone and improve nothing.

I.e. that culture of pragmatism needs to be defined as part of the expectations process, not an unspoken promise between coworkers. No process is perfect but a footgun process is easy to make anyways.
