A YouTube video about Echoes of Wisdom used the phrase "outsmarting the developers", which I think really encapsulates how players feel when they first use the spider to crawl up a wall "escaping" the normal path boundaries.  Of course it's all an illusion.  The developers knew this was possible and created the game to encourage exploration outside the "normal" boundaries. 

And while they are subtle, the walls are still there.  It's impossible to escape the Sauthorn area until you've closed the Sauthorn Ruins rift.  You can only create 3 echoes and the cliff & forest around the area is just a little taller than you can reach.  (And even if you were able to, apparently there's an invisible wall around the area.)  Once you close the rift you can explore the whole of Hyrule - except the three Goddess rifts don't exist.

Given this, I suspect that 99% of the "discoveries" made by players were anticipated by the developers.  This may even include the "bad warp" glitch which allows players to warp to the end game after completing the first rift.  The reason I think this might be true:

1. One of the objectives of the game seems to be to give the player the feeling they have "outsmarted the developers" (even when they haven't).
2. The glitch does exactly what the speed running community would want - skips over the majority of the game.
3. The process to trigger the glitch is very specific and yet was discovered shortly after the games release (intentionally leaked maybe?)

On the other hand, the speed running community has years of experience finding glitches and this glitch seems to have similarities to other glitches (where multiple game driven actions are occurring simultaneously).
