I don't think anyone has a problem with some botemless pits, in the newer games, especially sonic unleashed and rush, they build the whole game around the concept that you can only die by botemless pits.
The old games encourage you to play careful because there are a lot op traps and your just stupid if you think you can play the classics like sonic rush.
Before entering that huge botomless pit section, a wall stops you going through that section. So if you fall in the botomless pit, it's basically your own fault lacking skill in precision platforming with sonic's controls.
However a lot of newer games throw the botomless pits at you without warning, this happens the most in sonic unleashed. It ends up making the games more of a trial and error/qte/memorization game. Not fun.
