Hi Scott,
the nearest match is something that you have to enable explicitly, so it
won't be available if you don't enable it.
The default value is always there, but you can specify a value by hand that
does not match anything.
In recent versions of GeoServer, you can match that with having GeoServer
throw an InvalidDimensionException
when there is no match:
https://docs.geoserver.org/latest/en/user/services/wms/webadmin.html#dimensions-settings
That's for WMS. I don't remember what WCS does, off the top of my head, but
I'd guess it also throws an exception
(I'm hopeful for WCS 2.0, less so for 1.1 and 1.0)
Cheers
Andrea
