How do we make "None" go away? There are 3 options I know of.
Add a fake whitespace option, and mark it the default
When a select list is marked required, and has a default value, then 'None' disappears (https://jira.atlassian.com/browse/JRASERVER-3666). So the idea here is to add a select-list option with value " ", and mark it the default.
This works, but breaks JIRA's enforcement of the field's required'ness. Users can create issues with the default value " " selected.
This problem can be avoided using ScriptRunner Behaviours, setting an error on the field if its value is " ". This works, but Behaviours is bypassed by the REST API and Automation for JIRA.

Don't be tempted to use a JIRA translation plugin to map common.words.none to to '', as that will break many other uses where 'None' is the correct meaning.
