https support for mainframe Natural?

Somewhere I think I saw that SAG was planning to support https calls using REQUEST DOCUMENT from the mainframe.

Does anyone know an approximate time-line for general availability of this feature?

In the meantime, have any mainframe shops developed an alternative method to get to https resources from Natural on the mainframe, via a proxy of some kind?
