The most common way to split a string in lines is using this concatenation formula.
Is it really? I tend to avoid it in favour of ””” or ‘\n’.join(<list of lines>), because it looks like a mistake.
Triple quotes are kind of annoying if the string is indented, but you can just not indent the string to avoid the whitespace.
No footgun potential, and as others have mentioned the “good usage” would often be bad simply because it ends up looking like a mistake even if it’s intentional.

2to3 could also trivially add +, and if anything, that would actually help surface these kind of bugs, because if you randomly see a + in the middle of your list of strings, it's much easier to spot the bug than if there was a missing comma.
Preventing a bug that occurs in 5% of observed codebases (and anecdotally, happens to me during development all the time) seems like about as good as reasons get.
Swapping a perfectly fine print statement for a function, on the other hand… that’s the breaking change in Py3k that’s never seemed worth it to me.
