That is not a change likely to get accepted, because BITS_POST is not a
standard method. It is both proprietary and custom extension method.

What we will be looking for is a fix that solves it for all other such
methods as well. The Squid parser needs to be correctly handling the
method as an OTHER_METHOD object with a custom string as the actual
on-wire representation (not "OTHER_METHOD").
