I'm personally a fan of a very short idling type warmup, and then "gently" driving the car until the operating temperatures are reached.
Cold engines have really poor combustion characteristics, so the sooner you can get a bit of load on them, the better it'll warm up. Note: I'm not advocating going out and banging through the gears at redline to warm it up, but drive it slowly and GENTLY until it's at operating temperature. This is especially important for the gearbox and its synchronisers.
Regardless whether it's carbed or EFI'd, in order to get a cold engine started and running requires a pig rich mixture, which doesn't do the rings & cylinders, lube oil, catalytic converters, etc. any favors. And sitting there idling isn't doing anything to help the gearbox warm up, either.
We could probably take some lessons in warmup from the large industrial engine companies, who require jacket water heaters, lube oil heaters, and prelube systems for their standby diesel generators, fire pumps, etc. which are required to start and take full load in 30 seconds or less. Both coolant & oil are preheated to 150F (+), and when the start signal is issued, the engine is prelubed for 5-10 seconds, then the starter kicks in.
I'm a big believer in prelube systems for cars that sit for long periods, and am going to incorporate such a system for my 550, and may put a lube oil heater in the dry sump oil tank as well.
(My views are based on 6 years in field engineering & packaging for that company that builds the big yellow engines, and 2 years with one of its competitors in their central R&D)

High mileage, low compression, and missing on a few cylinders.....just like my cars.
