I disagree. By having curly braces you end up up doubling the number
of closing braces required. While I'm not a parsing expert in
Asterisk, I believe something like the following would be easier to
read:

Original:

exten => 100,n,Goto(${IF(${EXISTS(${DB(foo/bar)})})}?:novalue)

Proposed(?):

exten => 100,n.Goto(%IF(%EXISTS(%DB(foo/bar)))?:novalue)

You end up with half the number of closing braces, and is much easier
visually on the eyes.
