Hello Michael Collinson,
I see you used site_type=industrial and =building on a number of edits of yours recently. site_type is deprecated, which makes its use a bit unfortunate, your dozen of edits being the only objects worldwide carrying this key-value combination.

I know there is more to it and I am sure you have reason to not put those object under historic=archaeological_site to begin with. But would you agree to use the archaeological_site=industrial or =building, repectively, which have come to replace site_type= and are widely in use?
