I highly suspect that it affects a small number of clients but that these clients could easily become orphaned. Another option I thought of this morning is to disable update staging on Beta for Windows only for this release. This is only a pref flip, is something we've done in the past, and is extremely safe.

This would ride the train from Beta to Release and staging would be re-enabled when the current Nightly that contains the fix for bug 1596778 makes it to Beta and Release.
