As I understand it, deferees votes don't count, and if you don't "un-defer" by 30 Jan and announce your allegiance to the mother ship once again, you're not going to get any of the bennies (whopping 2 years of LOS!!) of the current proposal. You can still stay deferred until the 3 year clock runs out, but you miss out on this sweet deal.
I'm sure I'll be corrected if any of the above is wrong.
Staying away...far away.
