Because like you said, things can change.
Tho the end of the crowed funding campaign would mark the transition to retail release.
It also marks an end for backers being able to adjust their fleet any further which means any ships you have you are stuck with so you need to be sure they are the ones you want.
Currently you can melt ships for store credit to get a different ship ect, once crowed funding is over, your fleet is locked in and can no longer be tinkered with because you will then have access to them in the beta environment in a big and persistent way.
So knowing exactly when that cut off point will be is pretty important to backers and that information needs to be 100% accurate. So they can plan accordingly to insure their expensive fleets are set up exactly how they want them.
Releasing dates for things that have shifted internally has burned CiG a few times already, the biggest being Star Marines spring release.
December 2016 was likely a rough estimate on when things would transition to live beta, they obviously do not have that date narrowed down enough to want to say that is when it is going to happen.
But there will be an end to crowed funding and it will likely mark the beginning of beta, or a phase in beta when they no longer plan to wipe the servers.
We know they plan to do minimal wiping during beta and only when it really needs to happen but at some point they are going to be confident enough to no longer issue a wipe during beta, they could choose to end crowd funding at the beginning of beta, or wait until they decide 100% on no more wipes to lock in every ones ship purchases.
I am more inclined to assume crowed funding would end when initial PU beta begins, an not in the middle of it since they likely would not know if a wipe is needed until some exploit is found. and if none are found then they would not need to wipe so it would be better to lock everyone's ship choices at the beginning of beta.
