Formally, we can merge it today. Historically, every update of OS caused us instability for some time: from days to a couple of month. Taking this into account and number of other exceptions requested, overall stability of code, my opinion would be to postpone this to 10.0.
Also, I'd suggest to change the process, and have freeze date for all OS updates no later than a month before official FF date. This will give us time to stabilize, and ensure that base on which all new code is being developed is stable when approaching FF. I'd also propose to have freeze for major upgrades of 3rd party packages no later than 2 weeks before FF, which Fuel depends heavily upon. For instance, such will include RabbitMQ, MCollective, Puppet.
