Yes. But even they are becoming rarer as the 1x with a moon-sized large cog craze has taken off. The rise in popularity of "bikepacking" (minimal gear, usually off-pavement) has also spawned the "adventure bike," which often comes with a double up front. The Trek 920 is an example.
I'll stick with my triple for touring, thank you, despite Mr. SRAM telling me I have been doing it all wrong all these years. The only thing worse than not having a low enough gear is not having close enough steps when climbing long distances with a full load, possibly on dirt/gravel.
