How do you remove a stack?

[kiliandbigblue]

I have sucesfully used stacked PRs and ultimately got all the PRs associated with my stack merged onto the default branch of my repo. But gh stack checkout keeps showing them and I don't know how to get rid of them, except by doing a gh stack unstack <slug>, which is super tedious because it doesn't support auto-completion.
Thank you for the help!

Maybe a slightly different question, what is the expected workflow after all of the PRs have been merged? Is it unstack? unstack seems a little like the wrong thing, maybe finish or complete or close the stack.

We released an update to gh stack checkout in v0.0.8 that automatically filters out merged stacks. After all the PRs in a stack are merged, it is considered complete and can no longer be modified or added to.
