That's a pretty cool glitch.
Doesn't seem like it would make the game more challenging though. You'd just have to rely on land travel, and looking for things manually rather than using the sensor. It would be a pain in the ass, but it would just be time consuming, not difficult.
If you weren't able to use runes at all, that would be different, as you'd be stuck with 7 hearts and no extra stamina for the whole game, and some required parts of the game would be harder without runes. But then you'd have to find a way off the plateau without using the paraglider since that would be unobtainable unless there's some other glitch that allows you to obtain it without completing any shrines.
Some people might consider it challenging to beat the game without using fast travel, but to me it would just be torture running back and forth across the map many times over
