The cons are the extra complexity in the language, reflected by extra code in lread.c, extra code in elisp-mode.el, extra text in the lispref, which will probably be followed by bug reports about some cases where using a raw string literal doesn't work as it should (for code that's analyzed at the text level rather than the sexp level, I'm thinking here of code that does things like `grep '(foo "' ...`. I can't think offhand of such things, but I wouldn't be completely surprised if it shows up maybe when we collect docstrings for the etc/DOC file, I also suspect changes will be needed in edebug.el, possibly in pp.el, ...).
