Every time we will rerun pip-compile, these dependencies will be added again, right?
If this is the case, I don't think it's worth it to remove them and instead simply close the CVE saying that it does not apply

Also, pyJWT was just approved by security to be used without any need for further approvals.
So at this point we could consider to use it.
