That method was not introduced for users to use and was part of internal machinery that was ripped out

https://requests.readthedocs.io/en/master/api/#requests.Response.is_permanent_redirect ?

I think an alternative check for the first history item being a permanent redirect would be a more accurate way to calculate this? The actual permanent redirect url would be gotten from the last permanent redirect among the contiguous group of initial permanent redirects. Maybe?

@SoniEx2 I believe autoclass will auto-document a public method. That doesn't mean it's encouraged for you to use

Could we get it removed from the docs? It's hard to expect developers to consider a documented non-leading-_ attribute private... Or implement it more sensibly (based on my minute or two of thought, maybe I'm missing something).

it does add value fwiw - if you're doing things yourself.

but don't rely on it as representative of the whole response chain.
