There's a long thread on something similar here:

https://mail.python.org/pipermail/python-ideas/2018-March/049564.html

Carrying over into the following month:

Here's an even older thread:

In the more recent thread, I suggested that we give strings a dedent method. 
When called on a literal, the keyhole optimizer may do the dedent at compile 
time. Whether it does or not is a "quality of implementation" factor.

The idea is to avoid the combinational explosion of yet another string prefix:

    urd'...'  # unicode raw string dedent

while still making string dedents easily discoverable, and with a sufficiently 
good interpreter, string literals will be dedented at compile time avoiding any 
runtime cost:
