I understood the aim was to mimic IE's implementation? Which will
return a 5 digit code in the 12xxx range from WinInet for errors not
returned by a server)

Of the 5xx 504 is more justifiable than 502, as then you can pretend
the browser is simply a proxy which has timed out,  502 which
specifically mentions an invalid response doesn't sound a good idea.

I believe Safari now has a 1 year timeout, so that could be an
interesting test to run on a release build :-)
