Allow any quoted string to be multiline?

"Protection from bad coding" is about the strongest argument for a language
feature as there could be. Even features that allow doing "more for less"
have the ultimate advantage of reducing the chances of coding mistakes. I'd
say it's the basis of every modern programming language and framework
development out there. I'd be interested to know of any counter-examples if
you disagree.

(small example: arrow functions referencing the outer `this`: avoids
mistakes caused by possible different nested `this`es. I can go through
every feature to show how it reducing the chances of programming mistakes,
but it would take too long)
