 You can use the example code below, then in the current development code:

 1/ Navigate to the new Widget Editor
 2/ Paste the code below into the browser console
 3/ Place this Widget in your Sidebar
 4/ Move the widget to 'Inactive'
 5/ Try placing a new copy of the Widget in the Active sidebar - note that
 you can't do this until the Inactive instance is deleted.

 I probably agree that's it's not a blocker but it is likely to create core
 and plugin support requests while users get used to the new Widget screen
 and realise they have to tidy up the Inactive Widget lists to add new
 Widgets that are only allowed a single active instance.
