Actually the SQL one is arguably in that category too, to a lesser extent. Libraries could, and should, make it obvious how to do parametrized SQL queries in your language. I would guess that for every extra minute of their day a programmer in your language must spend to get the parametrized version to work over just lazy string mangling, you're significantly adding to the resulting vulnerability count because some of them won't bother.
Bonus points if your example code, which people will copy-paste, just uses a fixed query string because it was only an example and surely they'll change that.
