Failing a time control option just because your dexterity is incapable of even playing a casual game with it simply reveals your incompetence. Many games are played in 1/2+0 hourly and there's even a scheduled tournament for it with success, known as the Hourly Hyperbullet. That's a decent hint that you should not play it, not that everyone's obligated not to play it.
The main point of the discussion should be trying to distinguish what makes 1/2+0 different from 1+0 to warrant a new category, which is currently only limited to how the bullet community isn't fully adapting to hyperbullet yet and losing rating. As with how 5+3 players who aren't comfortable with 3+0 can just... Not pick that time control, the aggregate factors in 1/2+0 are only slightly worse than 1+0 or 0+1. If anything, I feel the difference between 1+0 and 1/2+0 is just as much as between 1+1 and 0+1.
