I would call it "Switch off all vendor parameters" because it is hard to guess which parametes may cause troubles with WMS servers. In the case in mailing list it was not DPI but MAP_RESOLUTION which made UMN Mapserver v. 5.0 to fail.

The one who knows can add whatever vendor parameters to server URL, but because most probably they are not advertised in the GetCapabilities user should also be aware to use the base URL instead of the GetMap url from GetCapabilities. It gets a bit difficult for regular users. Would it be too bad to have "vendor parameters" box in the already crowded dialogue?
