I think the second problem has been solved through game design- nobody (at least, nobody sensible) makes platforming segments in first person games anymore. Half Life 2 and Metroid had them, but soon after that they died out because people realised that they were awful.
I only realised that nobody does them anymore during the Duke Nukem quicklook, when the Giantbomb guys were marvelling at the platforming segments ripped straight out of the late 90s.
There are still games where you need positional awareness, don't get me wrong- Portal, for example. But I don't think they need as much pinpoint accuracy as previous games once did.
