Sure, you have a few extra newlines and semicolons, but the minifier will remove them anyway so no harm.

These are fine and do not cause any issues.

The only "issue" it has is that its unfamiliar. People have been working with HTML for years and are comfortable with it. That's basically the only reason that people find it more readable. If you make an effort to spend sometime with hyperscript, it becomes as familiar and readable as jsx.
