If the site goes HTTPS fully, I think the Keyword Data is still passed though. I might be wrong, its been a while.
For me it would be easy, since I write my own code, including keyword analitics and pages visited, real time too :), just flip the switch in validation to allow access to the site only thru HTTPS and redirect all crawl-able content to be crawled via HTTPS protocol only.
Google: Keywords tool will not be available without Adwords account

I honestly don't think G is shortsighted enough to do something like that system wide for the sake of obfuscating seo efforts. Websites would have little incentive to look to Google for traffic or optimize for Google. The focus would no longer be on Google for optimization. We wouldn't know what or how to optimize for keywords - optimization would be shots in the dark. Our only option would be to look for other big sources of traffic [webmasterworld.com].
