When will Breeze support ANY filtering (where predicate on children relationship)?

When will Breeze support ANY filtering (where predicate on children
relationship)?

We have a need to select records based on the value of a related child
table's properties. I discovered today that this feature is supported in
odata with a keyword called 'any'. Further it's supported in the default
breeze server implemention (using entity framework). Using the same server
that my breeze client does, I can enter an odata query in a browser using
the 'any' keyword and select records on a related child's field value. For
example:
.../Issue?$filter=oIssueImages/any(ii: ii/IssueImageRef eq 4)
And it works! But, there is no support for this in the breezejs client code.
FWIW: I found this breeze feature request:

Anyone know when breeze will implement this feature?
