I don't know about the NG, but on classic I'd still go for TOGA below 2000ft RA (since it's inhibited above this height) just to go out of the approach mode, because it's the most simple way to do it. A/T would then command thrust for rate of climb between 1000ft and 2000 ft/min and if you're close to MCP altitude it would go into ALT ACQ very soon, so no particular discomfort for passengers. But I agree - pressing TOGA twice and following FD pointing into stratosphere to climb for 500ft until missed approach altitude is not the way to do it.
