Please do remind them, though, that not stripping the closing newline (which is what was originally proposed) *and* not having the option of using `\` to elide newlines (which is contrary to what was originally proposed) would mean that all multi-line strings would mandatorily end in a newline.

To clarify, the core team's decision is that one trailing newline should be elided before the closing delimiter. This maintains one consistent rule for both ends of the literal, so """\n and \n""" can be mentally understood as balanced delimiters. as Xiaodi noted, it would otherwise be impossible to write a literal without a trailing newline without scope-creeping the design with additional features.
