Hello Bob,
you are doing PPP over Frame-Relay.
first idea:
the command could be hidden by a change in defaults with the new release so you don't see it but it is still effective
second thought:
you can configure a default static route in global config using the virtual-template as outgoing interface to get a similar result
see

This command allows a PPP virtual template to dynamically add a default route pointing to the virtual access interface created by the virtual template.
A customer premises equipment (CPE) router with PPP over an ATM or Frame Relay connection can access the Internet without turning on any other routing.
So if you are providing a default route in another way or using any form of dynamic routing over the PPP link I agree it will not be a problem.
Hope to help
Giuseppe
