Please provide any additional information below.

For developers who want to create a branch from a tag, let them make an active choice. Those who just want to switch to a tag and miss to uncheck the box 'create a branch' ends up with a mess of cleaning(remove unwanted branch). For those who want to actually create a branch from a tag and forget to check the box, can correct this in the next step without any harm. For all of us who want to switch to a tag in production environment, there is a risk of unnecessarily cleanup work from the current default behavior. So make sure that the default behavior for the check box is not checked.
