OP has a detailed rationale for going with semicolons. Feel free to counter those points, but you can't just dismiss the thing with a "doesn't look right" without any argument.
The first point is addressed in the article; you don't seem to address OP's counterpoint at all.
I don't get the second point: why is that a problem if a semicolon appears in a comment? From what I understand, comments run until the end of the line, so a second semicolon after the first does nothing.
The problem is when a config value includes a semicolon, and the rest of the line gets ignored unintentionally, especially because strings aren't quoted
Ah, I see, so the problem is not a semicolon "used in comments", it's a semicolon used outside them. But then which character would you suggest instead? The article notes that there is the same problem with # (e.g. in `black = #000000`) and // (`url = https://en.wikipedia.com`). And these are arguably more common.
