Simple way to handle a single concurrent workflow

Is your feature request related to a problem? Please describe.
I'm looking to create a task queue that needs to handle at most 1 workflow of a specific workflow type across workers.

Describe the solution you'd like
I think something like this could work for one worker:

we.RegisterWorkflowWithOptions(MyWorkflow, workflow.RegisterOptions{
  MaxConcurrentWorkflowsInWorker: 1,
  MaxConcurrentWorkflowsAcrossWorkers: 1,
})

But I'm not sure this would work across all workers. Any idea?

Describe alternatives you've considered
I took a look at this, this, and this.

I think these solutions are too complex to implement in comparison to the solution described.
