change, unique node names could only be enforced by running the
command "extract unique", and there was no way to ensure that
the user would run the command as part of the extraction
recipe. Now that it has been changed to an extraction option
instead of a separate command, and does not permanently alter
labels in the layout like the standalone command version did,
it is possible to include the setting in "extract do all",
making it run by default, and requiring the user to manually
turn it off for certain use cases (which are relatively rare).
