I don't deny that this is a gotcha, but you misunderstand the purpose of
raw strings. They weren't designed so that Windows users could enter
pathnames with backslashes. Raw strings are designed to enter regular
expressions, and for regular expressions, not being able to end a string
with a backslash is not a bug but a feature.
