Does SCCM 2007 work with SQL Server 2008R2 SP3?

It's not listed as supported at https://technet.microsoft.com/en-us/library/ee344146.aspx

Stick with SP2 (or better yet, upgrade to ConfigMgr 2012 from a 7 year old product).

Thanks Jason. Would love to update to 2012 (or 2016 later this year), I've even done the training. Just waiting for someone to give us the resource to do it. Sigh.
