Oh.

The text about singular paths is only about comparisons (they were needed so paths can be used to yield singular JSON values).

I missed that the grammar now also limits exists-expressions to singular paths.

Are we sure that this is what we want?
There is no reason for this limitation.
(Well, unless you want to rule out using exists-expressions for checking “at-least-one” conditions.  Which I didn’t know we wanted.)
