I also disagree with this proposal.

While I am sympathetic to your reasoning, I believe it is flawed.  This 
project exists to record the reality on the ground, not to attempt to 
influence it.  In this instance, poor planning on [your] part sadly does 
constitute an emergency on [our] part.

On the bright side, as a volunteer project, we are under no obligation 
to respond to emergencies in a timely manner.  We don't have to put out 
the fires.  We merely have to record when they happen.  We don't make 
any commitments about how soon we respond to emergencies.  We shouldn't 
make any commitments about how much time needs to pass between
