Hidden Tracks

I'm talking about the final track of an album, where there is an extra track included after a long section of silence. Does anyone still fall for these anymore? I can see maybe ten or fifteen years ago, when people weren't using digital formats, but even then, with a decent CD player, you would know that there were still 4 or 5 minutes left in the song when it “ends.” What's the point of doing that now, when all tracks are time-stamped and the length is usually staring right back at you for the duration of the song? Why not just cut it into a separate track, as I sometimes end up doing myself? If there is that one person in the world who exists who doesn't bother looking at the time remaining on a song, wouldn't that person just end it when it gets to silence and miss the extra content anyway? I can see the purpose when a live track, raw cut, or outtakes of some sort were included, but often there is just an entire song thrown onto the end of another, for seemingly no reason. Perhaps it is an issue of cost, where the artist wants the song to be released but studio costs are too high to make anything more than one or two takes, with some rough editing, although this is clearly not the case with the vast majority of hidden tracks that I've heard, which again makes me wonder, what is the point? It's perplexing.
