Tldr;
  Deleted no. modified yes.

There is always an entry for the all zeros address (a.k.a the default route) in 
the IPv4 and IPv6 FIB. Principally this exists so that in the data-plane after 
looking in the FIB for a match there is no need to say ‘if 
(matching-entry-exists)’, since as a last resort, it will match the default 
route. In the absence of any modifications, the forwarding result for the 
default route is to drop the packet – which is presumably the behaviour one 
would want if the default route could be deleted.
The default route can be modified via the CLI or API like any other route.
