### Technical details about the JWT "subject" `sub`

The JWT specification says that there's a key `sub`, with the subject of the token.

It's optional to use it, but that's where you would put the user's identification, so we are using it here.

	// its only a possibility in orchestrated deployments with dynamic
	// DNS. Following code ensures that we treat if one of the endpoint
	// says its local for a given host - it is true for all endpoints
	// for the same host. Following code ensures that this assumption
	// is true and it works in all scenarios and it is safe to assume
	// for a given host.

an older Go version, the Go toolchain amends its defaults
to match that older Go version as closely as possible.
For example, when a Go 1.21 toolchain compiles a program,
if the work module's `go.mod` or the workspace's `go.work`
says `go` `1.20`, then the program defaults to `panicnil=1`,
matching Go 1.20 instead of Go 1.21.

Because this method of setting GODEBUG defaults was introduced only in Go 1.21,
