I didn't touch OpenBSD from, let's call it, the latter half of George Bush's presidency through the first half of the Obama administration. My first install of OpenBSD in years was a moment of "oh this old thing still?" followed by "huh, that was just as easy as I remembered."
It's all about audience. OpenBSD's installer is a thing of beauty for technical people. I can see where it would be daunting and texty to someone who's never touched a command line, but that isn't the audience.
At this point, I feel forcing technical users through a plodding GUI install wizard is as cruel as making grandma install OpenBSD with a complicated RAID configuration and volume encryption.
