they are valuable as a way of storing verified information.

i'm not depending on random mappers to guess at access restrictions. the 
goal is
the description of verified data. so let's propose that the access=emergency
description in the wiki look like this:

use access=emergency only when emergency access can be verified by a posted
sign or by reference to local statute or policy. example:

source:access=McKownville FD, Guilderland NY

there is already provision in the project design for a local policy file 
that can
supplement data in OSM in cases where such data isn't viable or 
appropriate for
OSM, but it would be nice to put verifiable data in OSM where appropriate.
