Initial quality is just one data point in a purchase decision. It is not meant to be a sole determinant of what to buy. All it tells you is how likely you are to have to bring your new car back to the dealership to fix some stuff that slipped through quality control at the factory - things like loose grommets, rattles, paint blemishes, some light bulb not working, dead speaker, infotainment system acting up, etc. However, the more of such issues a new car has, this might indicate lower overall quality and more problems down the road.

also, long term testing may not tell you about a specific model, because like you say, it would probably not be made anymore, but it certainly tells you about the brand. If a particular model had no, to relatively few problems within a specified amount of time, it's a pretty good bet it's replacement will likely be just as reliable...
Yeah, I wish that was the case, but I just don't believe it is so. Today, with each new vehicle model a lot of new technology gets introduced, some of it taking time to iron out while customers are used as guinea pigs... think of direct injection, CVT, driver assistance technologies, etc. This makes reliability of new/replacement models unpredictable.
