if you talk to the old man on the tower before you activate it, he will first teach you about scope and pins and then the second time you talk to him he will softlock you.

Whats the point though? It would just be another arbitrary not leave the plateau run

Late but there are indeed runs of this (I have one as well).

I know that in Wind Waker HD, there's a Softlock% where you are infinitely voiding out under Grandma's house, so it would be a cool concept
