I think there is a point: (a) the block folding option (as I think it's called elsewhere) is buggy -- it doesn't seem to handle nested if's correctly, sometimes mis-matches parentheses, etc. (b) Several times, I've accidentally collapsed a block trying to highlight an entire line (using the far left margin). It's annoying to have to open the block back up and find the line again. This needs to be an optional feature, I think.
