The proposal moved out of Flight Standards on 10 Nov, as planned. There are still another 6 weeks of admin coordination. However,... the FAA still hasn't determined the mechanics for how to implement the rule.
For former miltary IP's, it could go a number of ways. For example, let's say your last military checkride was 5 years ago. Is that the date they put on your new CFI certificate? If so, it would be out of date when you get it. However, the good news is that to renew it, you could take a checkride with a DE, since it would not be an "Initial" Instructor checkride.
As for the medical provision: do you carry a copy of your military medical? Or maybe not carry anything, but just have to provide proof within a certain amount of time if you get a ramp check? Don't know yet.
