Changes between Version 2 and Version 3 of Ticket #28104, comment 4

v2	v3
1	1	I looked into this and implemented option 2 but just want to note that the RFC link applies only to `PUT` ''in particular''. `POST` and other unsafe methods can return validator headers as discussed in [https://tools.ietf.org/html/rfc7231#section-7.2 Section 7.2].

3		I do agree that computing it for POST would make the code a bit ugly due to needing to run the functions twice and can be thought of as a new feature (I haven't thought through the feasibility that much yet) instead of the bug which is this. I could also use some help framing this in documentation (does it warrant a ..versionchanged, technically it does change things so I wasn't sure if it should go in 1.11 or not).
