Has anyone any experience on how Google handles 307?

I was wondering what would be the best way to handle temporarily disabled items. There is 302 and 307 and from what I understand 307 redirect is the HTTP 1.1 successor of the 302 redirect.

Any one has any experience on how Google handles 307? 

I am thinking I 307 the temp disabled pages to a generic page like site.com/we-are-adding-some-final-touches-to-this.html where we will explain to users why an item would be disabled and will give them an option to get notification when it goes back up.

Finally when it goes back up I remove the 307 redirect and make the page live.
