[Talk-GB] ITO path designation map & designation=unclassified_highway

[m902]

I notice that the ITO path designation map 
http://www.itoworld.com/map/87 says it supports 
designation=permissive_footpath (& bridleway).

Would ITO consider adding support for designation=unclassified_highway also?

(See Robert Whittaker's page 
http://robert.mathmos.net/osm/prow/designation.html)

Of course, this is not what is in the UK Tagging Guidelines, but I 
prefer this method of tagging.

Thanks
Martin

PS The ITO path designation map hasn't been updated since at least last 
Friday. How frequently is it intended to be updated?
