The f-strings are a recent (may be not so recent now) addition to the language, so all the errors stem from it being "new" where people's reflexes / carefulness hasn't adjusted to them yet.

I think in addition to the suggestion for linters, updating IDE/editors to incorporate them would help. Syntax highlighting is the primary reason not terminating strings isn't that common of an error anymore, coloring it differently than a normal string might help (or may be it would make things ugly, I don't know).
