I'm not a big fan [...] limiting them by date
There's flexibility and risk in there in that those works can be relicensed to cc-by-sa-3.0 *or* "future copyleft versions of that license".
This gives Wikipedia and Creative Commons some flexibility that's probably very valuable for them. They can tweak the licence if they think it's necessary or if the Wikipedia community demands it.
But it creates some risks to the freedom of GFDL'd wiki'd works, and it's a one-way relicensing that isn't being reciprocated by Creative Commons. With an endless timeline, this would be foolish and even dangerous, but by limiting it to a 12 month period, the risk becomes pretty small.
...I think.
