Surprisingly, quite a few! There is a new "version" called QB64 that has some extra commands and features that actually make Qbasic gamedev more practical. In particular, the _PUTIMAGE command lets you drop in graphics instead of having to create graphics with LINE and CIRCLE statements. There is a BASIC Game Jam currently in progress as well.
Now all that being said, yes, Qbasic is perhaps still a bit primitive for modern-day Gamedev -- I've certainly seem some of its limitations. But for those like me that grew up with Qbasic and already have a good understanding of it, it sometimes makes more sense to stick with what you already know than to start from scratch with something else.
Thanks for the comment!
