There will definitely be a standard non-blocker version, don't worry about that. Offering it is just a way of indulging a niche aesthetic preference, which, although I don't personally share it, is very much the whole point of projects like this for me: to make wacky, extravagant products a reality that would never happen otherwise, and to please my keyboard pals. I'm too addicted to modifier keys and shortcuts to forgo my Winkey (or, rather, in my case, the Apple meta key), but I do kind of dig the retro aesthetic, and just the pure nerdiness of it.
Whenever I'm puzzled by some form of human behavior, I find it helpful to think of it in evolutionary terms: perhaps winkey blockers are like the peacock's tail, a resource-costly form of masculine signaling--as if to say, "I'm so reproductively fit, I can get work done without even needing two of my modifier keys."
Thought of another way, it's also like riding one's bike without touching the handlebars: not strictly speaking a good idea, but still kind of cool anyway.
