On distillery tour in Scotland, the guide suggested new legislation afoot to allow reused barrels in bourbon production - any truth???

So, I was recently on a distillery tour in Scotland, and of course there's the obligatory discussion on the use of different barrels in aging whisky over there. The guide focused in on the economics of bourbon barrels versus sherry. He made a comment that there was potential legislation in the US that would do away with the requirement for virgin barrels for bourbon, and he mused that it would have a huge impact on the Scotch whisky market (let alone the bourbon industry). He didn't state it as a hypothetical... he made it sound like a fact.

I haven't seen or heard anything about this, and it seems highly unlikely. Anything on the horizon that anyone has heard or was he just speaking out his... ?
