The reason it's there is because, even inside r-strings, backslashes
still escape quote characters. To remove it, you'd have to either
disallow quotes embedded in r-strings, or come up with some other way
of flagging them without compromising the rawness quality of
r-strings.

Maybe you could have w-strings for Windows pathnames, that would be
*required* to end in a backslash... :-)
