I'm missing something here. Please ignore if I'm wrong.
The function says it does not do validation and the algorithm can be arbitrary chose, yet, there is a validation param and the validation step. So it's kind of partial validation.
I find it confusing and is not what #401 calls for.

Ah i was not completely sure that was the case as the creator of the issue wanted essentially this API:
``rs
let mut validation = jsonwebtoken::Validation::insecure_without_signature_validation();
let payload = jsonwebtoken::insecure_decode_without_signature_validation::(token, &validation).unwrap();
And IMO then a Validation::insecure_none or similar should exist to make this function more general.
Nonetheless the Doc comment is wrong so thanks for pointing that out!

The function description says "the claims are not validated", but they are.

JWT has 3 parts: Header, Payload, Signature.
The existing code refers to them by those names:
let (signature, message) = expect_two!(token.rsplitn(2, '.'));
let (payload, header) = expect_two!(message.rsplitn(2, '.'));
It would be good to keep them consistent throughout the file.

As discussed here adds support for insecure_decode_without_serialization as well as a doc test for it. I also fixed some doc warnings while at it.
