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.

What about three simple rules to define comments:
1. If # is in the first column of the line.
2. If # is followed by a space.
3. The # only starts a comment when it’s outside of quotes.
