The existing project https://github.com/dgrijalva/jwt-go had no module support and was likely imported as:

github.com/dgrijalva/jwt-go v3.2.0+incompatible

There was also a v4 that never got fully released.

go get github.com/dgrijalva/jwt-go@v4.0.0-preview1
go get: github.com/dgrijalva/jwt-go@v4.0.0-preview1: invalid version: module contains a go.mod file, so major version must be compatible: should be v0 or v1, not v4

Since users would import a new module anyways, one solution could be drop all existing versions (14 total) and start with a fresh v1.0.0 (hopefully no breaking changes required).

For many of my projects I see this being a basic search/replace operation:

- github.com/dgrijalva/jwt-go v3.2.0+incompatible
+ github.com/golang-jwt/jwt v1.0.0

The version in this case is irrelevant afaics.

Lastly, I am not sure whether the original repo will get "transferred" or "archived" (see comment here), but if it gets transferred then this might change the outcome of how to proceed adding module support?

Thoughts, suggestions welcome.
